clutch porn, plus install questions



Ok so resurfaced SLP flywheel, modified pressure plate and clutch disc courtesy of Tampa clutch supply.
Now the questions! I guess it seems a pilot bushing is better than a pilot bearing? What should I be purchasing and where, advanced auto parts does not carry a pilot bushing. There are so many options on Summit Racing its making my head spin.
Clutch did come with a alignment tool, from what I understand I will have the clutch installed properly if the alignment tool will slip through the clutch disc and the pilot bushing? Never installed a clutch before, engine is out of the car, will this make it easier to install? Anything I should look out for when putting the motor back in the car??
I've also thought about having one machined out of Derlin but I'm not sure of it's heat limits, without the heat factor derlin is a really good self lubricating composite material.
Whats the best way to install the bushing? The motor that is going into the car came from a A4 car, so I guess I don't have the joy of removing one, just installing.
