Lastly, should I be looking into putting in forged piston now?
There's a few
JE Forged Pistons and
Wiseco S52 Piston Kit, E36 M3, 3.2L, 13:1 CR

s54 M Coupe = 11.5:1
s52/s50 M Coupe = 11.3:1

What would a higher 13:1 compression do?

You will be fine.
94 M3 uses 3.15, that's correct, but 94 M3 GT uses 3..23 and 321hp M3 uses 3.23
