Good advice. In a coop expect to see every new/old/weird bike ever made, and every owner will want you to have that special tool that he can't find or afford.
Also, don't forget chairs, work bench/tables, tool boxen. It really adds up. You will want at least one really good work stand. You might augment it with a couple of $50 cheap stands. Also need at least one truing station.
Steel rules, at least one caliper, anti-seize compound, lubes, cleaner, ad infinitum... Then start listing spares.
