I'm part of this "renewed interested in chess", as I've played competitively when I was in high school but then stopped for several years until I came across this year's championship a few weeks ago. I've tried several things to get back into chess but so far I've gotten the most "bang for the buck" on http://chesstempo.com/ http://chesstempo.com/ , go to Training > Chess Tactics. It's fabulous, it feels very useful and it's even highly addictive. And for chess videos I warmly recommend ChessNetwork on YouTube. Lastly, I found a really nice app on iPad just called "Chess", which lets me squeeze in quick games in-between events and it's optionally computer assisted, which can help find interesting moves.
