Firstly, welcome! In your quest for info and ideas, also include the P1000-5 LE, as most mods will apply the same as on your -3. Most will also be the same with some lesser cost models as well as with the SE I bought. What I did is used the search function to get info on each upgrade I did. I copied some ideas and on some stuff, like light bar brackets, I made my own.
The SE comes with a winch, front bumper, and is wired for heater & windshield wiper (no switches for that stuff installed, but the wired plugs are sitting behind the provided accessory switch panel). Here's a couple of the projects I've done.
Made my own light bar brackets so the curved light bar doesn't block any of the top of the windshield, yet is as low as possible relative to front edge of roof. Also brackets are not through bolted, I used rivet nuts.

Dual purpose rear bumper. (Since photo, I've added a cover for jack mechanism and a foam handle cover for the jack.
