I was curious to see how many third parties made it onto the ballot here in Virginia, so I went over to the Virginia State Board of Elections.  Here are the candidates that will be appearing on the ballot in Virginia for U.S. Senate:

• Jim Gilmore (R)
• Gail Parker (Independent Green Party, and still the best campaign theme song ever)
• William Redpath (Libertarian Party)
• Mark Warner (D)

I can't find any mention of presidential candidates on the SBE site, but according to Ballot Access News, the following presidential candidates should be appearing on the Virginia ballot:

• Chuck Baldwin (Constitution Party)
• Bob Barr (Libertarian Party)
• John McCain (R)
• Cynthia McKinney (Green Party)
• Ralph Nader (Independent)
• Barack Obama (D)

(Yes, I intentionally linked only to the third party candidates... I didn't think you'd have a problem finding out about the Democratic and Republican candidates.)
