I'm trying to go boosted on my 2008 silverado with a 6.0 n I was trying to figure out what is all the requirements if someone could lost them 1 by one thanks

 

The parts you need or want will completely vary, it all depends on what you want to run.

Turbo, hotside, cold side, intercooler, injectors, bov, couplers, fittings, hoses, map sensor, boost gauge, wideband etc etc etc. And like 500 bucks for other random crap that might be needed for getting it going.

Read up on different threads to figure out what you may need, look up turbo kits that a sold by vendors and see what they sell with them. That will get you an idea of what you must buy.
