Factions: 15 Point Attribute Quests + 2nd Profession (POSSIBLE SPOILERS)

Hey guys, ok so 2 questions in factions

1) I did the first 15 point quest on the newbie island but is there a 2nd one?
2) Can I change secondary class once I leave the island?

I assume this is like presearing in proficies so when I leave I cannot go back and want to make sure I hit everything.....

You can go back as you wish0
And the Second attribute quest is also on the Island.
1) Lost Treasure (going back into Emperor's Estate from the Ran MasuGardens)
2) Unwanted Guests (Going back into Zen Daijun from Seitung Harbor)

In Senji's Corner, after the mission Nahpui Quarter, you can change secondary.
