craftsman would be a very good choice, have a loot at their large mechanics'/bodyworkers' sets too, lots of tools and excellent value.
from what i've heard, Craftsman air tools are very good too. i'd say a 1/2" drive air impact wrench would be perfect, and a 33-gallon compressor would be just right.
for impact wrenches, you need impact sockets. (thicker walls,
always in a black finish) never use chrome vanadium sockets with an impact gun, they can shatter and that's pretty dangerous.

an oiler is essential, it adds a little oil to the air going to the tool, this lubricates the internals like the turbine in the impact gun. you mayb also want a pressure regualator, which prevents "spiking" in the ait pressure going to the gun.
you'll need to choose the hose(es) yourself, depending on size of workshop, whether you want a long straight hose, or a coiled one or whatever.
this is the page with the accessories, it has all the hoses in there, hopefully that should help. when choosing these things, it's probably worth going to your local Sears and having a look at them, picking them up and that'll help you decide.
