It all depends how comfortable you are wrenching on your car really
A 5 speed swap would need :
Time
Patience
5 Speed trans
Differential (i think or else your revs would be crazy high)
Master cylinder (Clutch and Brake pedal)
Driveshaft
Flywheel
Clutch kit
theres probably more but thats all i could think of right now Its deff doable though
The classified would be the best place to get some parts and whatever that could be shipped is a good option too (unless you dont mind paying for shipping and handling for big heavy parts)
Pelicanparts.com is a good site for OEM parts
Check the sponsor sticky has almost every site you could find parts at
