I'd say she could probably skip Disassembled and House of M if she's already gotten to Civil War, though. CW is a good jumping on point, anyway, though kind of awhile back.
I guess, Cheshire, it depends on if you're wanting to do trades or monthlies. If you're doing trades, I'd stick with getting some Dark Reign and Siege stuff (Secret Invasion was okay but can also probably be skipped). If you're doing monthlies, three new Avengers books are about to launch that will all be great jumping on points.
