I was just wondering, is it possible to get 100% completion without doing Via Infinito. It just takes too much time. If not, does anyone have any tips of making the trip though it easy?

Nvm I've a new a question. I was wondering if I can access Via Infinito if I had done stuff in the Farplane. Like if I leveled up in the Farplane and boarded the Airship, can I go back to Via Infinito? Is the boss you have to defeat in the Cactuar Nation hard? Is so, can I do the same thing by leveling up in the Farplane and then come back and fight the boss?

mod edit: don't double post.
