Sorry that I keep confusing you x.x
The thing you gotta remember is that you want to have your ST fit you. Since MP characters have a 35 SP limit, you can try Practice mode with the character and try to set the desired skills under that limit.
The goal of this is also to determine the useful skills from the useless skills, distributing limited SP among the Basic, Skills, and Shared tabs of the ST accordingly.
If you do screw up, you can always by SP reset cards, but that requires cash, of course... But you can start now, and if you screw up, Seeker's update (Zero's 2nd job) should allow all players with a Mass ST reset, as they did with Dio's arrival and 2nd job, as well as Ley's arrival.
Hope this helps.
