eclipse tranmission?

i have a eclipse that just had its clutch replaced by a crappy guy it could be a old clutch not sure though it looks like he busted at least 2 trannsmission bolts need info on fixing that (easy out?) it grinds every once in awhile and it also makes a bad sound when letting off the clutch like a loose disk is spinning around would this be from the busted bolts and do you think another problem has been made?
