A lift and 35s are each going to adversely effect your gas mileage. I think a winch and recovery gear would be a better buy for you, along with some really good 32" tires if you don't go with the stock BFGs. And traction devices "lockers, LSDs, etc.) if you don't go with a rubicon.
If you wanted to get a little extra stance, appearance, and clearance, go with a 2.5" coil lift and 33s. Check out my jeep in my profile for that look. It won't hit your gas as much as 35s and will still give you room to flex under 2.5" of lift.
Beyond a certain point, big tires and lifts are more about flexing and driving over big rocks than they are for trails. Search YouTube for "jeep j8." It's the military version of the JK, and it's got a lot of extra features you won't have (D60 rear axle, leaf springs, diesel, etc.), but it also only has 29" tires I believe. Take a look at what it drives through.
