Help!?! Just took apart my 360, and found bad things!

Thanks guys you rule! I don't have the money for all this as of yet... This project I guess may just take a bit longer. Always something.

Are these "Sealed Power" pistons any good? $400.00 for this set seems fair, and just may be the way to go? Are these equal to stock or a bit better?
