What tire size do you plan to run?
What are you going to use the Jeep for? (dd, light trails, hard core crawler, street queen, etc)
What exactly do you mean by adding beefed up axles? Upgrading stock axles or swapping for stronger ones? The reason I ask this is because you will be much happier if you regear before the tires, or ideally at the same time. If you want to upgrade existing ones you could just regear. If you want to swap in axles, you need to do it before wheels and tires. Or at least before wheels. That way you can make sure the wheels fit (bolt pattern, caliper clearance, correct width & bs, hubs fit inside wheels).
