Don't forget to watch your weight! Unless you don't care :P You mentioned a few pretty heavy things.
I'd guess that Fab Fours rack is ~200 lbs by itself. Throw a tent on it and your gear in the bed, and you are already over your payload capacity. Lots of people don't seem to care, but it's a good reminder.
If you are just camping and not going for serious offroading, you probably don't need a winch. I offroad a fair amount and have only had to use my winch for recovery 3 times. Your truck is REALLY capable, and unless you are doing some really stupid or intense stuff you'll be good without it.
