I did a small 2.5" Chase kit from BajaKits. They also have a full pre-runner kit but that gets pricey.
New BajaKit Upper Control Arms run around $850 - $900
King 2.5 Coilovers w/ reservoirs - $1400 - $1500
King 2.5 Piggybacks - $850 - $900 (these are optional but I wanted the adjustment ride option but once I found the setting I liked, I haven't messed with them).
The pre-runner kit is like another $2000 - $2500
I did it all when I had 200 miles on the truck.
To stuff 285/70's (32") under there I had to change the front bumper and do some trimming since wheel wells are kind of squared off. You can fit 265/70 without much trimming.
Just depends how high you want to go. Even this small lift affected my mpg most of it probably due to the size and weight of the big tires and heavier bumper.
I probably added several hundred pounds to the weight of the truck. The Kings take a beating though. I take it out to the Desert out here with my boy's dirt biking and I can follow them over small whoops at around 20 - 25mph without it feeling like a washboard and beating the crap out of me. Also good clearance for rocks out there.
Here's what it looks like.
