What about the final moves and stuff? I see them in the skill list..but so far I have not seen them come up on the battle window. Do I need to keep building up those dots that determine how many attacks you get in order to use those?
Well, once you get your first flurry to max level (7 skill ups at first) you can link it to the 2nd flurry. Meaning you hit Y once, you do both Flurry #1 and Flurry #2 for the cost of one turn.
Once you level up your second flurry to max level (7 skill ups at first) you can link it to the 3rd flurry. Meaning you hit Y once, you do Flurry #1, #2, and #3 for the cost of one turn.
At that point, you have more points than you can use and usually after hitting Y twice, your Final Move comes up. The Final Move usually is very cheap to skill-up so you can wait or do it whenever, but this is how it shows up.
