the omnibus edition of brubaker's run does a pretty good job of getting newcomers up to speed on cap and his characters. even though he's been around since the 40's he hasn't really had alot of books in print concurrently until a few years ago, so you could probably start with #1 and work your way forward without too much trouble (as opposed to what you would find with batman/superman/spider-man)
