Hi Dan:
You are correct, every day above ground is a great day.
The commode comes out easily, with the caveat that disconnecting the water supply is the hardest step. You have a seal on the floor that might benefit from replacement, and, depending upon the age of the commode, I'd get a repair kit for the commode's water switch. If you are removing the commode it is a lot easier to rebuild it before putting it back.
The hole cut through the floor is large enough to get a good view of what is in your tank. I'll pass on the details.
