I can't believe that most everyone is putting safety towards the last of things to do, or even completely leaving it out of the list altogether.
Since this is going to be the OP's DD car, I would do ALL maintenance work first (belts, hoses, TB, WP, etc, etc, including rotors and pads if needed). After that, I would focus on SAFETY. New tires if needed and a roll bar.
Just like I did with my BRG, first and foremost, I made damn sure it was road worthy as I drive it 100+ miles every day, five days a week. Guess what, it hasn't let me down once in the past year that I've owned it, which I've put well over 29k miles on it already. I would not hesitate to hop in it right now and drive from Florida all the way to Alaska and back... Twice!
After getting all the maintenance stuff out of the way, I still had enough cash left over for a new suspension. The BRG had the original 20 year old, tired hardware under it. The rear shocks bottomed out a lot (actually, I was riding on the bump stops 95% of the time), but it was still safe. The only reason I chose the suspension over the roll bar was comfort. I was tired of being jolted all the time like riding a 10-speed bike at 75mph for 100 miles a day. LOL
Safety is next on the list, even for me. I've been wanting to get a roll bar for the longest time, but $$$ is what's holding me back. One of these days...
