Now, back to that bad/blown Therm-custoff fuse, I do not see a reason for it just blowing unless it is getting too much heat back-blow from the burner. Is it possible that the flame being out of adjustment could have caused the issue? Or might the t-stat also be bad and have something to do with it?
that's exactly what happened with our WH (same model as yours). the thermal cutoff (TC) had blown and once I bypassed it the WH worked again. I picked up a couple of new TC units, used one to replace the bad one and kept the other as a spare. they are very inexpensive and EZ to replace. beyond that I would adjust the flame as needed. and you don't need a by-pass wire...just connect the brown wire from the control board to the TSTAT terminal.

Would it be wise to replace the t-stat and the thermal cutoff fuse at the same time, or is that overkill?
overkill in my estimation. the gas flame can be adjusted so replace the TC, adjust the flame and go from there.
