Anyone know the absolute maximum total configuration time for the 10k10? ( POR + EPC1 configuration time). I seem to recall it being somewhere around 320ms but don't know if that includes POR time...

I had a dig around in some old Altera application notes and found an old one with the numbers you want. This info might be in other documents too, but since the app is no longer on the Altera site, I'll upload it here. I searched for POR and DCLK and found the following (you can read the app for details).
From AN116:
1) p9 EPC devices have a 200ms (max) power on reset.
2) p42 PORSEL delay 2ms or 100ms (depends on your board)
3) p6 EPF10K10 configuration size is 118,000-bits, p32 DCLK maximum 16.7MHz, so about 7ms configuration time.
That's 307ms, so your estimate of 320ms seems reasonable if you're using the longer PORSEL setting.
