Alright.
Closet Auger didn't work.. It just did a U turn and came back toward me, it didn't go the whole way around the bend.
Removed toilet. Wax ring looked ok I guess, a little odd. The DW is going out to get a new one.
The flange was 1/4 inch above the flooring on one side, and just below it on the other.
I was able to sent my auger (drill operated) snake down though, but I heard it in the wall, so it went up the vent, not down the drain.
I took off the trap under the sink and sent my auger though there, but I got stuck at some point and couldn't advance further (couldn't hear it, but it went out toward my garage). No clogs there, just brackish water.
The DW will also be getting a wrench for me to open the stack access pipe. I am hazarding a guess that they installed a T instead of a Y or something, which would be why my auger went up the vent instead of going properly out to the clog/septic.
I'll update you guys after she gets home.
Also,
You can drain the toilet with a bailing sponge or even on old towel. Soak, wring, repeat. Once the toilet is drained, you an remove it and snake the drain. It might be gross. But, you're washable.
I've worked with blackwater systems on a certain Tall-Ship that I volunteered with, and I'm not afraid of the blackwater. I just was trying every avenue I could before remove the toilet. it never had any leak issues untill it had a back-flow, so If I could resolve the draining issue I'd be able to deal with that at a later time. It looks like I didn't delay it much!
I'm not sure how to count this.. Since there is 'so much stress/going on' I told the DW to pick up a pizza on the way instead of cooking dinner, I guess We'll see how it turns out in the end. If I can get at it from the access line, and clear the clog, then we'll subtract it from what I would have paid a plumber. If we can't... well, I guess that'll just be some stupid tax/unmustachian cost!
