If you have a used OEM Flywheel I would definately get it resurfaced. Also a clutch install isnt hard.
Torque the flywheel down using this pattern.
.......1........
....3.....5....
....6.....4....
.......2........
Then put on the clutch disc and pressure plate. Not sure the specs for those but I am sure someone will tell you.
Then put the tranny on...
