Welcome aboard. I think you're heading in the right direction as far as pre-trip maintenance goes. You could find the tail light for sure in a salvage yard. The rest looks like it would be fairly easy work for a body shop.
Have a safe trip and adios for now,

Is there anywhere in Vegas that has a good selection of E30's?
I pulled the pan today, luckily no bolts. Changed the oil, trans fluid, new plugs, and the only 14mm socket I could find was too long and I couldn't get a wrench in without hitting the tire well. So the diff fluid is going to have to wait.
I'm going to do the coolant tomorrow.
While I was under the car I got a look at the suspension, trans mounts, guibo and such. Everything looked OK so that stuff can go down the list of things to do.
