HIn Tony, that hour is not wasted at all. Time taken to learn a skill; is well worth it and it has shown you that the correct tension is so important. Thats why setting up without any guides anywhere near the blade is essential.
I made exactly the same mistakes you have made when I started and I guess most of the other members did as well, so count it as a plus, not a minus. The 1/4" and 5/8" will be good, particularly from Tuffsaw. Good luck.
