Welcome! We take pride in having a friendly forum, we are nothing like those Honda/VW forums.
Wet passenger floor is usually because of water getting in through the cabin air filter. Simple fix is to install the rain-hat extension. Check to see if yours has it first, and if it doesn't, go pick one up at a junkyard. Don't pay Ford $35 for a new one, its just a piece of plastic. It's under the passenger cowl.
Having a new transmission is a definite plus, and with regular maintenance you should find the car is a reliable, comfortable and practical ride. Good buy for sure!
