Crossover, speaker alignment, room equalization - what do I start with?

MSO calculated the delay to put on closer subwoofer.

If you want to keep it that way, measure each sub separately. Far sub as is, near with MSO delay, using acoustic synchronization over the same speaker with the tweeter. Then do the addition of the measurements in REW. You will get the measurement of the combined sub. Second option. Turn on both subs together, the far one as is, the near one with an MSO delay. Make measurements with acoustic synchronization over the same speaker with tweeter: combined sub, left front, right front. 3 measurements. Next will be job on choosing the crossover frequency.

Yes, with timing reference as you did for MSO and yes to XO in place.

Thx! another question if you wouldn't mind what is the correct way to measure subwoofer when using acoustic timing reference? do I set measurement frequency range to operating range of the subwoofer? SVS is 260hz -+3db, do I measure that range? or full range? there is a difference in the delay measured with full range being about 1-1,5ms more, that is quite significant.
