You ask some very good questions, many of which I have asked in person at the Consulate in San Francisco. Here is my best understanding of the responses I got.

a). If she Registers at the consulate in Seattle, can they perform the ZAGS function of registering her marriage too?
Yes, if both people who married in the US were Russian citizens and were married by consulate official. Otherwise no.

If not, then which ZAGS would she have to go to, since she has no registration anywhere else?
She technically would have to register anywhere in Russia. Go to the local ZAGS there with the translated, "apostilled", and Russian consulate certified (they tie all the documents with a string and place a seal / stamp with a signature on it) marriage certificate and have them do it in Russia.

. If she Registers at the consulate in Seattle, can THEY change the name on her internal passport to her married name?
No.

c). If she Registers at the consulate in Seattle, but they will NOT change her name on her internal passport, then how does this happen, since at this point, she has no registration anywhere else?
Refer to my answer to part (a)(2).

d). If she Registers at the consulate in Seattle, but they will NOT change her name on her internal passport, will they at least add the "insert" to her international passport indicating her new name?
Yes, they did it for us.

e). If she Registers at the consulate in Seattle, will they issue her a new international passport to replace her expiring one?
I don't think so. As all internal passport issues are handled in Russia.

f). If they do issue her a new international passport, and by some miracle they change her name on her internal passport too, then will they issue her a new international passport in her new name?
Once, again, they will not do anything with the internal passport. But if she does register with the consulate they will forever renew her external passport in her maiden name.
You mention not doing anything and waiting for the US passport. It’s a good idea if she no longer wants anything to do with Russia. Because even with a US passport she will not be allowed into Russia itself because she is a Russian citizen with an expired Russian passport or lacking a Russian visa, which she cannot get unless she abandons Russian citizenship. Also, if you are late in renewing your passport the Russians have the audacity to charge you more fees.
Good luck getting responses to these questions over the phone. It was hard enough in person and I still don't understand all of it. Not to mention Russian laws change often and with little notice so all this information could be obsolete pretty soon.
Finally, this processes seems daunting enough when you live 30 minutes from the Consulate, I can’t image the problem of flying in from hundreds of miles away and trying to do this. In my experience it usually takes several trips to get anything done with the Russian officials. The only good thing about working with the consulate is that they are the only official. While in Russia the document scramble could cover lots of “official” places.
And to top it all off, what are the Consulates doing about children who were born in the US who got official citizenship through their Russian parent(s). These kids don't even have internal passports, how would they get their external passport changed to a married name? Crazy system!
