If I deauthorize all, can my wife just "authorize" the home iMac and my large library stay intact? I assume, but am asking, will this affect the iPhone and iPad which syncs with the iMac at home? I need to cause as little drama at home as possible.
I completely understand your desire to keep the drama to a minimum. This Apple KB article will tell you more about authorizing and deauthorizing: <http://support.apple.com/kb/HT1420>.
The simple answers to your questions, in order, are: yes and yes and no. But read the KB article first.

Now, I'd love to get all that music at home, onto to my MBP and Mini here in Afghanistan. Flying home is out of the question for this year. If I turn on Match, does it have to be turned on at the house's iMac to get the music then sent to my MBP and Mini? Right now, I see the "Cloud" has my MBP as the only registered device. I looked at the FAQs and poked around, but I don't see a way to add my Mini or iMac. I don't have the subscription *yet* but when I do, I want to make sure it's not going to blow out my home (iMac) collection. I have wayyyyyy too many hours spent ripping my CD's to iTunes.
This is actually, just what iTunes Match was designed to do. However, there are some quirks to the service. Basically, your wife would enable iTunes Match on one of the computers and let it finish it's initial scan, match and upload process. This may take anywhere from a few hours to several days. Then enable the service on the other Mac at home. Let it finish, then you can enable it on the Mac with you. Let is finish the scan, match and upload process. Then enable it on any iDevices you want it active on. All this will take some time, and I mean possibly a few weeks depending on the sizes of the various libraries and the upload speeds.
