Beef ribs are my favorite.
I smoke them at 250 until the meat pulls back from the bone. I don't foil my beef ribs. I don't find it necessary. I do spray with a mix of beef broth and whatever seaonings I want about every hour after the first hour. It depends on the size of the rack but I've found it averages about 4 hours.
As far as what wood to smoke them with, it depends on what you have available. Mesquite, oak and hickory are all good choices. If you have some cherry use that in addition to the wood of your choice for a slightly sweet touch.
Good luck and don't forget to post some qview for us to drool over.
