Don't forget food, the freeze dried stuff is pretty good in the woods. Make your own first aid kit- you can do it better and cheaper then buying- keep it in a ziplock freezer bag. Candle lanterns are also a nice light light source for in-tent reading.
The more stuff you lug, the more you want to dump it all and go home.
Have fun!
