Ok, I finally got into the Cabelas site. I am going to stick with my recommendation on the Exped Synmat 7 or 9. They are slightly thicker and much lighter than the Cabelas pad though I don't know if weight and size are an issue for the camping you are going to do. If not, then you might consider a more rectangular sleeping bag as mummy bags are pretty constrictive.
As for the tent, if you are going to be in cold weather, consider a tent with aluminum poles. From my research, the fiberglass poles can break in freezing temps. The other benefit to aluminum is they make repair kits that is basically a sleeve you can put over bent poles to keep them from bending more. This of course is for field repairs until you can get a new pole.
