What are the basic things I need to go off roading in my 91 Jeep Wrangler?

I dont do no major off roading just minor stuff like muddying and old wheeler trails and hills. I have a 1991 Jeep Wrangler Has cat back exhaust and header and 31" tires and a 3" body and 2" shackle lift. Is there anything else I should get to make the jeep a little better off roading? Im not looking to spend a ton of money so I'm looking for just basic stuff that might be a must have or something like that.
