If you aren't going to be off roading much, there is little justification for long arms. The 3.5 would be fine for your application. You would be able to fit 32's with some bumper trimming. This setup will take you pretty far as far as occasional offroading goes.
Edit: off the top of my head, there wont be any issues you would definitely run into.
