I'd say keep it stock for at least a few months but ideally for a year or more. During that period catch up on any maintenance items and make sure the rig is baselined. Suspension bushings, steering tightness, etc. are among the items that may need attention and may take a while to sort out.
During your "stock" operation period make notes on your planned build and you'll likely watch it evolve over time. Desired tire size, lift height, bumper/armor, lights/accessories, etc. seem to change as you read on the forum, check out other rigs and learn how you use your 80. Some folks start out wanting to go big but end up appreciating a closer to stock height rig. Other folks wish they would have jumped straight to 40" tires and all the changes required to run them. There aren't really right or wrong approaches but you can save a lot of time and $$ if you avoid building multiple versions of your rig.
The main exception I'd consider to the "keep it stock" for a while plan would be creature comforts like cup holders, sound system, seating repairs, power outlet additions and similar. There are some creature comfort areas that may benefit from long term thought, like the sound system or interior wiring plan, but most of these are low risk and high value in my opinion, regardless of where the build ends up. If you regularly have passengers they'll really appreciate spots for their drinks and ways to plug in their devices.
A big benefit of running stock for a while is that you'll get a feel for how the brakes "should" work, how the suspension and steering geometry "should" feel, how much power the engine really has with stock tires, etc. Even small changes of 1" in tire or lift height will impact acceleration/braking and balance/stability a little. I personally think it's important to consider all aspects of a setup changes and not to overweight factors like appearance/cosmetics, which is easy to do.
Good luck and share some pictures of the new rig!
