I went to Egypt a few years ago and had a blast. I would check out Cairo (obviously), Alexandria, Aswan, Luxor and everything in between. Consider taking a cruise down the Nile with a tour guide from Aswan and Luxor.
Just go out and by your favorite travel book on Egypt. My personal favorite was the Lonely Planet guide. You also might want to take some dry food with you to munch on. For me, Egyptian food was awful.
