Should I somehow re-tooth my fret saw for a finger teeth count than 8? I feel it worked well enough... I guess I'll try hammer setting them and dialing it in a bit... I feel the saw could really benefit from a set because as it was it cut well even dull until the cut was deeper than the teeth, then it started binding.

I'm surprised that 8 TPI gave you a clean enough cut but if it did then I guess there's really no need to change.
Cutting fresh teeth in saw plate isn't really beginners stuff, although if you have something to practice on it's a very good way to learn how to sharpen saws. It also teaches you how to correct mistakes when they start happening. I brush Indian ink on to blacken the teeth. It works good if you let the ink thicken up first though.
There are templates online that give you a print out of different TPI, just glue them to the saw plate.
But it's always best to practice on junk saws. File straight across and concentrate on getting tooth size even. When I first started sharpening saws I made this 'tooth template' and indicator:

You see. There's those plastic teeth. You can cut a whole saw like that and not damage anything. Once I had the tooth geometry on the plastic correct I would simply sit the file in the gullet and then press the indicator onto the end of the file so that it was pointing absolutely vertical. Then I could transfer the file and the indicator to an actual saw. It's a good technique for learning. After a bit of experience you'll dispense with these visual aids.
If you get really good at it there may even be a little part time business sideline. For some odd reason LOTS of woodworkers are scared of putting a file to a saw.

I found a Bahco saw file locally, it wasnt cheap either at about 12 dollars a pop. Will see how it goes
