No PS3 game played without modification to the game can mess up your PS3. If it could be proven that it did the developers and producers would be liable for damages since it was advertised as for the PS3. Worn ,scratched unreadable game discs are a different story and the problems playing them could be considered messing up your PS3 only while using that disc
It shouldn't. Mine works fine. If something goes wrong try checking the controller setting in the JC2 pause menu.
No, it won't do anything.
No But They Can Mess Up Your Game

NO, it was ment for the PS3, but its always good to backup data every so often just incase.

If you buy a game that is for 360 and PS3 than yeah but if you put a a 360 game in a PS3 heck no that won't work it can mess up your PS3
I am pretty sure it does not, as it only uses the hard drive, it does not mess with the MotherBoard, as far as I have seen.
Yes you can, and it won't mess up your PS3 Slim warranty either.
