Need advice on what to do...

Looks like you are where I was last winter, a drivable porject. And it looks like we done the same thing. I pulled the front end off as you did Then motor/trans and all engine bay stuff off. Sanded, painted the bay. Cleaned, painted motor\trans, re installed. I sanded hood and fenders primed and painted the bay side and left the outer in primer. Drove it. I also was working on interior at the same time.
This winter is to do body work and prime in epoxy and hope to have all the done for spring\summer to finsh paint.
