VOTE

If it's important enough for Stephen Colbert to put into his opening titles, then it's important enough for you to do.

Get information on voting (where to vote, how to vote, what voting is):

U.S. Government

And from the candidates:

Obama: Voting information, more voting information, and reporting voting problems/voter protection.
McCain: Voting information.

Make sure to leave lots of time -- while your boss may have given you an hour (which is pretty awesome of them), you might need more time -- lines for just early voting have already gotten as long as eight hours. And while this probably will not be the case everywhere, you don't want to lose your chance to vote because you didn't give yourself enough time to do so. Also, remember that if you get in line by the time the polls officially close, you have the legal right to vote (officials will keep the polls open so that everyone already in line can vote).

All the best! Feel free to leave any questions or voting stories in the comments.
