Any options traders here? (need help)

Just messing around on optionsxpress with some virtual money.

On the expiration date, which is this Friday, how do I get rid of these things? Can I sell the option itself and where do I look to see what I can sell if for?

Also, the option cost me about $800, I can make about that if I buy the stocks and resell at the current price. With only 2 days left would it make sense to do that?
