I think the SAHARA mod in those years came with the fenders painted the same color, but
Finding one is a problem
Tire rim size has nothing to do with the tire size you pic (relative), if you get a JK 2dr then 32" tires are about the limit without lift (thats all you'd need), you can fit 33" tires with MODS, a JK 4dr will accept 33/34" tires with out a lift
You have to be careful with backspace dimensions and the need for "spacers", but that will depend on your choices
Tires are a little cheaper for 16" rim size, but thats changing, tires are real cheap for 15" rim size, but then you would have Brake caliper fitting problems, it's been done, but then backspace is important !!
If you're worried about cost stay with your wheels and look for some BFG A/T's and your cost will stay down
