Akkam’s Razor TL;DR.

Here's voters guides from Ask.com for Pennsylvania, New Jersey, and Delaware.  SmartVoter has some wizard-based guides as well.

Here is a list of links from the Resource Shelf.  beSpacific also has some resources to watch after the polls close.  PhillyFuture has more of the same from a local perspective.

If you are going to participate in VideotheVote.org or the Polling Place Photo Project, it'd be a good idea to check what the state laws are regarding photo-place photography (via BoingBoing).
