Jump Hero build?

Grrr, hate rebuilding my char, but I guess I have no choice.

Level 200, so I have all the SP I'll ever have. All 4th job skills at max mastery except Rush (20) and Monster Magnet (10).

Right now I'm thinking:
Swordsman: All max but Iron Body, again?
Fighter: All max but Physical Training (If I understand correctly and it still only applies to Power Strike and Slash Blast?)
Crusader: All max but Brandish (since I already have Intrepid Slash)
Hero: All max but Rush and MM, again?

Will I need a book for Advanced Final Attack, or will my Achilles turn into AFA automagically?

Physical Training actually gives 30 STR and 30 DEX, not buff Power Strike and Slash Blast, so I'd leave Ground Smash at 2. Even though it's beneficial to go with Ground Smash during 2nd Job, sacrificing a skill is the biggest flaw with Ground Smash.

For Crusader, If you're at a level where Brave Slash outclasses Brandish, you should definitely leave Brandish at 11. Otherwise, leave Self Recovery at 11.

For Hero, it depends on when you want use Monster Magnet or not. If you want to use it, I'd max it. If not, leave it alone. Rush and Monster Magnet don't need to be maxed. If you choose not to max them both, They will apply to the skills you didn't max throughout 2nd Job and 3rd Job.

Achilles turn into Advance Final Attack, so if you have a Mastery Book for Achilles, you should have a Mastery Book for Advanced Final Attack.
