I've seen the Fel Pro gaskets and prefer the GM aluminum gaskets. Both should work fine, just a personal preference.

Coolant elbows
Teflon paste (LIM bolts)
Brake cleaner (gasket surfaces)
Gasket scrapers
Ultra copper RTV (LIM corners)
TB gasket
TB cleaner (You gotta clean it)
SC to LIM gasket (aka listed as plenum gasket)
You're right it doesn't HAVE to, but there's not really a reason not to do it at that time if it hasn't been done before.
