So much to do, don't know whats next, need advice

Well, you have a pretty good list. I would start with getting the car running. The interior doesn't have to be perfect or complete to drive and enjoy the car. Make a list of ALL the things it will take to get it running. Then break it down to smaller projects. Don't jump from project to project, plan your work and complete a project at a time. It's very gratifying to finish a project. Go through the whole list the same way.

Exactly this. There is no reason to have a complete interior in a car that doesn’t run.

Once the car gets back from paint do the wiring and then the fuel and brake lines. Then do the suspension, then install the engine and the rest of the drivetrain. Then get it running, then worry about exterior trim and stuff. Then finally the interior. Install the interior before that and it’s just in the way, you’ll either have to pull it back out to get access to other stuff you need to finish, or it’ll get thrashed while you’re trying to do mechanical work. And if you buy it early you just have to store it. Same with the exterior trim. It doesn’t take long to install, it doesn’t accomplish anything other than appearance, and you can ding it up if it goes on early and you’re still doing lots of mechanical work.
