Just keep in mind that it is still a long term and fairly expensive project. The number one thing to do first is to do what you are doing now, research your options and get as much advice as you can get. You must also decide where you are going to accomplish this. And if you are going to send some of this work out what are those costs plus room for any unnoticed damage, breakage, worn out parts etc. After you have done all the research and gotten a much more realistic idea of what is involved then you should set up a realistic schedule.
Most people tend to do or have done the engine first.
But I recommend disassembling the car as far down as you have decided to go. That way you don't have anything but your time and some rust-buster etc. into it yet. Then you can get a really good look at how bad things really are that you may have not noticed before. Disassembly is a project in itself. During disassembly you should take as many pictures as possible and or use a video camera.
