The folks at Project Vote Smart have created a new site for the November races. It's a spiffy interface and covers most of what you want to know about the candidates, (those who've answered, at any rate). The Q&A's are pretty simple and cover about 12 issues. Might help you see where some of the candidates stand on issues. Obviously, the questions don't contain the nuances that a more in depth questionnaire would, but they do serve to point you in the right direction. Just click on your state, put your zip in and you're off!
