When a project only gets bigger and bigger

Best way I get things done is not in any particular order but focus on what needs to be done in order if Possible s a senif dreaded break downs or short comings while driving the car.

As a mechanic, I address engine (drivetrain) running quality first followed by suspension and brakes. Then electrical. Interior is normally last.
Body after interior unless there is a rot issue under the feet. Tht will be addressed before I hit the road as a driver.
