Nice truck. With 6" of total lift I would run a 35x12.5 on the 8" wheel would be a nice fit. I also wouldn't spend money on a 3" kit, save a little more and get a 6" kit and don't crank it up until you need a little more.
Lifting can add up quick if you do it right, here is a quick run down.
Lift kit 6" $1K +
new tires and wheels 35s $1500ish
gears front and rear, parts only with a locker $1K +
misc. parts that break or just need fixed as you go $300 lets say
Now keep in mind that is not including labor.
Now a body lift is $200 lets say and with that and cranking up your stock keys and a 2" block out back or there abouts to get the stance you like. for a few hundred bucks ou get a good look. Then throw some 33-35" tires on and be done with it.
Lots of options, my advice is to find a truck that you like the looks of. Show us that and we can tell you how to get there.
