I love YaBB 1G - SP1!
AFAIK the cutscenes in FFX cannot be skipped.
Zanmato instead of Trio? Are you mad? Good luck finding a) the cash and b) the turns against Yunalesca and BFA (as you'll need to use Zanmato three times and two times in those battles respectively). Also, getting Yojimbo is far slower than collecting the ingredients for a Trio Mix (from the Remiem Races compared to going through the Cavern Of The Stolen Fayth).
If there is time to be shaved off, it will be in the areas early in the game, I think (where battles can take a fair while e.g. Gui).
