tejon, in a setup balanced with omobs is there benefit in using ProgressSBSP?
Absolutely. Daggers are still faster than claymores with OMOBS, and since experience is per hit, that means daggers level you up far more quickly. That's what SBSP addresses.
Hmm, I can't see Thaumaturgy there, bad bad bad...
Hehe, hard to know where to put it. Is it the same as Mysticism? Does it belong dead center? I'm not adding any new skills, so I'm sticking with the default six schools and I've decided not to rename them. But my reevaluation of where to put each magic effect does include some re-investigation of Daggerfall, so there may be echoes of Thaumaturgy after all...
How (in)compatible is your latest Anyclass with GotNoClass?
Didn't actually test this until now... turns out they're fully compatible.

As you said, you need to select the blank class at character generation then use the
StartQuest AdoptAnyclass console activation. You can do this immediately, though be warned that nGCD and Skill Decay both assume a minimum of 25 for class skills and +5 for specialization. This shouldn't really hurt anything, you'll just suffer no decay to class skills until they exceed that minimum, and nGCD will calculate level 1 (with no progress) until you've gained 175 skill points. Low skills rise fast, but it'll still take a little while. That's the only downside I see, really.
Edit: ShowClassMenu doesn't appear to let you keep the Anyclass-adjusted blank class, you have to select the genuine blank again. This resets your skills. I assume the same will be true of Baurus, so best to wait until you've spoken with him to activate Anyclass.
If you're playing a race with less than 7 bonus skills, you'll get Combat skills filling any extra class slots, in alphabetical order. For the vanilla races, this usually means you get Armorer until you raise something else to 6. Nords already have Armorer, so they get Athletics. Orcs have Armorer and only 5 bonus skills, so they get Athletics and Blade. With TRAP, all races have 7 skills except Argonians (who, again, will get Armorer). Don't know about RBP's class skills.
Btw. Have you checked that Google spreadsheet I linked above yet?
No... actually, I just assumed it worked since you'd figured out the localization issue. Personally, I've done all that math a thousand times over.

Definitely a good tool for anyone who wants to play with the defaults, tho.
