Welcome and congrats on your "new" truck! I'ts better than anything I had at 16! Looks like it's pretty straight, so you have a good starting point. Just don't throw away those mirrors, they're probably worth something! Looking at that pic, I'd say get some hood adjusters to straighten the hood, and sand down the rusted spots and primer & paint them. Cosmetics aside, check out all the mechanical stuff - fill or replace all fluids, tune-up if needed, belt & hoses, brakes; make sure all electrical & mechanical things work properly.
And thank your parents! (You already did that, right?)
