RE: One issue that you mention specifically, front suspension replacement -

You have already ventured down a path that will make that task a bit more difficult. You have removed the subframe with the suspension still attached.

Many of us have found front spring removal and replacement a tad easier when you have weight of the car on the control arms.

However, there are several other tasks you need to evaluate with your car as disassembled as it is:

Brake and Fuel line refurbish or replace

Floor pan/trunk pan clean/repaint or replace as necessary.

Firewall clean up and repaint.

I also recommend spending A LOT of time on this site going through the Tech sections. There is a lot of history here of people doing restorations on these cars and the lessons they have learned the hard way.
