35's and re- gear or not to re gear and smaller

I am running falken 285 70 17 on my 08 rubicon 4 dr auto. The power is just fine for me. I have to get new tires and would like some larger like maybe a 35 ( ok well actually a 34.5 or so) I have a 4 inch lift. winch heavy front bumper It is a dd that i use in work off road. so my question is do i really need to re gear ? that will run at least 1000 and tires about 1200-1600. together that is 2x's my budget. I amin san diego area most of my off road is either dry clay, wwet clay or desert sand sometimes snow if I go play in the mountains.
so the questions :

A get something maybe a little large and live with it ?
B go with 35's and live with it?
C which tires I want an all-terrain.
D do I really need to re gear for 34ish tires/

Regardless of which gears you have now, anything short of 5.13 gears will annoy the hell out of you (and your 3.8L engine) on 34" tires, or larger... performance on the road would be dreadful, and off-road desert crawling would be painful, as well.

For tires, I suggest the 315/70/17 Goodyear Duratracs for an all-around well performing tire both on and off-road.

If you were running the 6-speed I would say go for it.
I have this combo (rubi) with the manual and it is a bit sluggish but nothing that bothers me. I hear with the automatic it is really a pain mainly due to shift points never matching what you really need. Pony-up the dough and go for it. A 4-inch lift with anything smaller than 35's looks silly if you ask me.

I prefer BFG All Terrains. The General AT2 is a great tire as well, a little more affordable.
Never had any experience with the Goodyears.
When in doubt...FLAT OUT!
