Question about order of operations for complete brake system bleed

[BTF/PTM]

Don't worry, I'm not asking about what order in which to bleed calipers/drums. I'm pretty sure this hasn't been asked before, I've done quite a bit of research. I won't have all the parts I need by the weekend to complete the whole end-to-end job, but I wonder about whether I can start it. My questions are:

1) Is there any reason I cannot check/adjust the booster push rod and bleed both the master cylinder and the warning light splitter block this weekend and then get to the calipers/drum cylinders when I've got all the parts on hand?

2) Is there a preferred order of bleeding for the MC and the warning light splitter block? I plan on bleeding each part at each bleeder valve, but I don't plan on disconnecting hard lines. Does the MC have any preference of bleeding the front or rear line first? The 280zx MC (15/16 size, PO installed) is reversed from the 240z unit, I believe. Not sure if that means anything specific.

For those who are wondering why I'm doing it, it's a continued venture of ruling out potential PO mistakes. It's taken weeks and deep pockets to shorten the list thus far of things that were done in a terrible rush with many corners cut. Thanks, everyone.
