I've heard some pretty good things about the videos, but then again I probably haven't done as much investigation as you. My tip is to not focus too much on having a powerful body. While important, the body is secondary to your lenses. Looking back on my purchase, I wish I could have gone for a lesser body so I'd have more to spend on a lens. That's not terribly important right off the bat though ... I used the standard lenses that came in a kit for over a year and they suited my needs just fine. Now I get lens envy though.
I'm not sure how much you fiddled with the manual settings on your point and shoot before, but if you haven't I have a book recommendation:
The digital photography book (click for link) by Scott Kelby is a book I've bought for several friends whenever they take the plunge and buy a dslr and they've all really enjoyed it. His writing style bothers some, but I find it to be a great way to learn. It isn't overly wordy or deep with explanation, just one tip per page for the entire book.
