It's a tough proposition on an older car. I just finished a 3 day marathon of claying/compounding/polishing/finishing/sealing. But yet, the divots and deeper scratches remain. Not much you can do on a daily driver. Given your other hobbies, I would be hard pressed to suggest washing it every weekend and maintaining the paint the way it should be.
That being said, you can do a lot of correction on a car and get it in MUCH better shape. Then, you have to decide whether or not you want to maintain it in that condition. There has to be a compromise somewhere.
From what you said, a religious program of washing/polishing/detailing is not realistic.
If I were you, I would pay a professional to get it back into shape and then maintain it how you normally do. IMHO, the best thing for a car is being kept in a garage at home and at work.
You could re-paint, but again, on a daily driver, your heart will break the second you see another chip.
Before you embark on a part-time job of detailing your car and the considerable cost that it will take, spend a while on some of the detailing forums and see what other people do. It will give you an idea of what you might be getting yourself into. I know, because I did the same thing!!!
