The garage will help tremendously. Maybe hold off on big projects until then.
Once you do have a place to park and work on the car, recognize that you need to park it for a while. Then come up with a systematic plan to get the car where you want it. You can do that two ways:
One - Total Frame resto, where you know the car will sit for many, many months (or years) as you tear down and rebuild/replace.
Two - Progressive, well planned Phases that focus on specific areas and systems. This will allow you to periodically drive the car and enjoy a bit as each phase is completed.
There IS a Third way - The way you are doing it now, the way many do it. Fix one thing at a time and drive it and see what happens and how far you can drive her!
I prefer #2, as it is safer and can be well documented. I have also done #3, which is alot of fun and mysterious, but could leave you on the side of the road on a regular basis.
