One thing I would actually recommend is using the CBR Comic Legends Revealed
articles to get some extra backstory behind some major things. (Actually, the Comics Should Be Good blog has a lot of good stuff you can check out.)
Toonopedia
is a fantastic resource that covers all the genres from the very beginning of the 20th century and before, up to the present. Only caveats: not all the entries are American, and some are primarily/only newspaper comics.

If you want to talk intelligently about the medium in general I recommend reading Understanding Comics by Scott McCloud
if you haven't already. As to actual history, I PBS
recently produced a documentary about just that. I don't know if it's any good but it's probably worth a look.

This is a book that I found very helpful, giving me a solid grounding in a lot of 40's comics history back when I was younger.

Not sure if this is worthy of its own thread, but...
So, long story short: I want to make a Web Video series about the history of American comic books. Does anyone know of any resources I can use to help me out?
I'm aware of the articles on the Ages of comics on this wiki, as well as what Wikipedia's got. Recommended comics to read, important facts/events that usually get glossed over in these types of things, general advice, I'll take whatever you've got.
