How long do I cook the boneless turkey and at what temp?

I got a boneless turkey (frozen). There are no instructions on it. I weighed it and it's 6.2 lbs. I read to cook it for 20 min per pound so I figure I should cook it for 2 hours. Is that right? Also, I just took it out of the freezer and put it in the refrigerator to thaw. How long should I leave it there? What temp. should I cook it at? I'm guessing 350, but is that right? Should I wrap it in foil? I don't need to have it done in a hurry so if I have to wait 24 hours for it to defrost that's okay.
