I've heard people talk about pryos being able to rocket-jump in TF2. Since they obviously don't have a rocket launcher, how is this done?
You need to have excellent timing and accuracy with reflecting an enemy rocket. You wait for the rocket to get close to you, timing the reflect to aim it at your own feet and jump and crouch, much like a Soldier would. Except it's not your rocket.

I saw there are multiple types of locks. Is it possible to remove any lock regardless of your lockpicking abilities? How can I improve my keyboard/mouse dexterity to have better success?
Does the game leaks information on the right position, such as through a sound or visual clue? If I make little tries, so as not to break the pick, is it possible to find the solution?
You can indeed unlock any chest regardless of your lockpicking mastery. Despite having no proficiency in lockpicking I was able to unlock a master chest that I found, albeit with great difficulty. As far as I can tell, your proficiency affects the speed at which your lockpick breaks, and perhaps the accuracy of where you have to slide your lockpick.
When you hit on the wrong position, the game makes a distinctive resisting sound and your lockpick shakes. As a result, the easiest way to succeed at lockpicking is to adjust your position a few spaces over to the right or left, make a very brief unlocking motion to see if the lockpick shakes or not, and if it doesn't continue sliding it in. If the lockpick shakes during the middle of twisting it in, don't change your starting position but instead just test going either right or left from the shaking position to see which direction is the correct one.
The correct movement will not change in-between successive failed attempts at picking the lock(but will change if you exit the lockpicking screen or reload your game), so even if your lock breaks, use the information you gathered from your last attempt to try and succeed with your next one.

From what I've been through so far, the hand-to-hand fights in Uncharted 3 seem to be pretty random and a lot of button mashing. It seems to be a lot of ☐ to punch, and the occasional Δ to counter, and sometimes randomly mashing ○ to struggle and throw.
Is there a consistent technique to taking down enemies faster? I know that if you can sneak up on someone, you can take them down quickly. And occasionally, some of the fights seem scripted if you're close to an object that you will smash someone into. But for the normal fights, are there moves, or combinations of moves that you can do to take the enemy down quicker?
As you've gathered, the basic melee combo is pretty weak. Drake will do more damaging combos if you swing at an enemy close to a wall, a drop or an object that Drake can use as a weapon. Alternatively, you can do a 'steel fist' manoeuvre; basically, both punch and shoot.

Now that the wrangler has been introduced to the engineer, the engineer can get to places previously unreachable. Is it possible to get propelled upward with just the gun from the sentry to take less damage? If rockets are used, is it possible to pick up the sentry immediately after rocket launch, so that you can take the sentry with you on the jump? What other tips do you have?
You can reduce damage and fly farther by jumping and crouching in mid-air as you shoot the rocket.

So, I noticed that in the Medical Pavilion stage of Bioshock, there is one hallway you can enter that has a quaint little machine in it. If you hit a button at the other end of the hallway, this machine starts shooting out tennis balls. There are various trophies lined up along the wall, and various Tennis racquetes littering the floor in this hallway.
Now, I did find what seems to be a fake torso hanging from a pole (apparently to study anatomy, as the front gives access to various organs) in another room on the opposite side of the area, which gave me a cool idea. After some work, I managed to carry him across the entire area and stand him in front of the machine so that the fired balls were then wildly deflected every which way, which was great at first: but now I want something more.
I've tried using the tennis racqets combined with the Telekinesis plasmid, but have been unable to do much more than launch it at the ball in mid-flight, sending both objects off into the far reaches of the next room.
Pretty sure the 'intended way' to play quasi-squash in that room is to just TK the balls back at the wall.
Far less fun than trying to hit them though.

I can't quite get the hang of this. I've been in a few maps where a pro was just demolishing everything like this. I'm asking for specific instructions with an xbox 360 controller.
To circle strafe with a helicopter in any game you have to understand some things about helicopter controls.
There are three main controls, the cyclic, the collective, and the pedals.
To circle strafe (or orbit while facing the target) you will need to tilt the helicopter to the right with the cyclic, while using the pedals to keep the helicopter pointed at what your circling.
To orbit to the right you would tilt the cyclic right, while turning the pedals left. In human terms, you walk leaning to the right(cyclic), and then keep your torso turned to toward what you are circling (pedals).
I'll try to translate to controller controls later.
Update for Comments: If the bird just spins like a top and falls to the ground then you are using to much pedal, and need to tap it less often. More likely you are loosing altitude as you strafe pointing at the target. This is normal helicopter behavior; I'll explain.
When a helicopter tilts in a direction, some of the force used to lift the helicopter is taken away to be used to shift the helicopter. This means you also have to increase the collective, or make the helicopter go slightly up while you execute the maneuver.
In most games there is a balance point of strafe and lift. This means you tilt(cyclic) the bird enough that full throttle (collective) keeps you at the same altitude. After that it's just a matter of rotating the bird (pedals) to keep it pointed where you want it.
Sorry, I haven't been able to translate to xbox controls yet.
