Camping is like sitting down. I sit down at home, I sit down when I am away from home. Probably a whole technology could be developed (actually it has) for at home and away from home sitting.
There is nothing to camping, you put up the tent, dump your mattress and sleeping bag in there and go to sleep. Sleeping is just a zen thing where you empty your mind of any crap that may be keeping you awake. You will notice different noises, but eventually you will fall asleep (or this won't even be an issue).
Ditch the pillows, just ball up some of your extra clothes and gear. This is early season yet for many areas, double check your temp rating on your bag. You can sleep with various clothes etc... Be sure to bring a beanie it will ad a lot of warmth. On the other hand, some parts of the US are pretty warm right now.
Have fun.
