Cooking a whole chicken?

I need some help. I have a de-thawed whole chicken for dinner tonight. It's 5.8 pounds, how long will it need to be cooked for and at what temp (in the oven)?? Also, we just moved in here and I don't have an oven roaster pan or anything like that, the only thing I have is a big Pyrex gl pan, would that be ok cook it in?? I wouldn't be able to cover it or anything. Ah, help me out!
