I recommend you sell your auto car and buy a manual one, because the time+effort is far going to exceed the value of your car. Okay, now that the obligatory smart ass response is out of the way:
You need:
-Pedal assembly
-trans (obviously)
-clutch assembly
-brake master cylinder from a manual car
-5-speed ECU
-clutch slave cyl
-clutch lines
-manual trans mounts
-shifter
-shift boot
-shift linkage
-shift bushings
-throwout bearing
I highly recommend you get a car from a salvage yard so you can get everything in one fell swoop, and buy aftermarket parts as you see fit.
This most likely isn't a complete list, I'm sure there are many threads about this, try using search next time, and when that doesn't work/ proves fruitless, make a thread.
