hey fellow PA jeeper! Welcome to WF.
I wouldn't spend the money on a winch right off the bat. You might not even need it, depending on what you're going to do with your Jeep. Skidplates however are always a good investment. So is a good tow strap. Run it for a bit, see what you need and then go from there. No sense in wasting money if you don't need to, and besides there will be plenty of things that you will just HAVE to get soon enough.
