For the Mighty Mask Event, you should have a full Mono-INT team with characters like INT Bulma and Tarble (for stunning and extra Ki).

And for Summoning, try to use this technique:

Single Friend Summon, Multi Friend Summon, Single DS Summon, Multi DS Summon

And if you get rainbow letters or have Goku turn Super Saiyan in anything but the DS Summons, start over from the beginning.

Then for your last question, the JP Version has a lot more characters, so you can switch over if you want.
