I went ahead and bought a 75g from petsmart with an AC110 for filtration. I know it's not ideal, and I could've gotten something cheaper if I would've waited, but I just said the h*ll with it and did it.
I setup the 75g, put some of the old water from the 125 in with new water, added Prime, aquarium salt and Stability, (here we go again), and I also took my scrubbies out of my sump and floated them in the 75g. I figure the worst that can happen is it might jump start the cycle process some. I'll remove them later tonight.
I also called my LFS and asked how much they'd charge to reseal the tank. They said they didn't do that, and all I needed to do was get some aquarium silicone and slap some over where it was leaking and refill, no need to remove the old stuff

Something tells me I'd be better off removing all the silicone in that corner and resealing from scratch. While I was getting raped at Petsmart for the tank, stand and filter ($435), I also picked up some aquarium silicone as well. The plan is to empty all the sand out of the 125 and this weekend get it moved to the garage so I can try resealing and then do a leak test before putting it back in the house.
Water damage wasn't that bad. I lost about 25g that went through the carpet and floor into the basement. Luckily it was over the unfinished side so nothing major got soaked. I'll pull the carpet back and get this are dried out hopefully in a couple days.
Now that they're setup in their temporary 75g home, all I can do is sit back, cross my fingers, NOT feed them for a couple days, and hope for the best.
