If you haven’t replaced the gas tank yet, do that first. You can’t drive it without gas The paint can wait.
How important are looks to you? If they are important, you can get a professional respray. I’d go with the same color to keep the cost down. You only need to paint the exterior that way, and not in the door sills, under the hood, and in the trunk. You can also keep the cost down my removing all the trip and taping everything the painter wants taped. You may need to remove all the exterior lights in addition to the trim. Don’t forget the grill and bumpers. It’s a lot of work, but you don’t have to pay them to do it. If this is beyond your skill level, you now know why paint is so expensive.
