It is do-able, but in my opinion not worth the effort. Unless you've invested a lot of money into your car or it has some sentimental value, you'd probably be better off selling the auto car and buying a stick car. You may even be able to get more car than you have now.. for example if you bought a blower car or one that had some NA mods already.
Anyway, on to the swap: you'll need at least the trans, bellhousing, clutch, pressure plate, flywheel, pilot bearing, TOB bearing, different yok for the transmission side of the driveshaft, pedal box, clutch cable, shifter, shift boot and shift bezel. It's a bunch of parts, so it's best to have a donor car or someone who provides the entire setup. It's not particularly fun working under the car either.
