After you defeat the boss: master of nu'un, go back to alltrades abbey and talk to the ghost in the basement of the abbey. The quest is actually simple, use the ability egg on on an ally in your team until he reaches a point of super high tension (tension of 100 and you must do it 4 times.)
What club? If you mean how do you equip clubs, you need to change to a vocation that can equip Hammers, namely the Gladiator and the Paladin.
you pick your vacation at alltrades abby
When you have defeated the master of nu'un and changed your vocation
The Courage skill tree is on the Warrior vocation.
Yes, there's no limit to the number of times you can change vocation.

Talk to the Priest outside the inn at AllTrades Abbey. He will give you a quest where you have to kill 3 slimes with 100 tention using dragon slash. To do this make your character egg on someone with dragon slash and let the others defend, if you keep egging on eventually you will get to tention 100 and you can kill it with dragon slash. Do this with 3 slimes and you should get the Gladiator Vocation. Hope this helped. :) (Make sure whoever kills the slime with dragon slash is the one who has 100 tention)
Your main character can freely change his or her vocation when you reach Alltrades Abbey, and solve a quest there. Until then, he or she must remain as a minstrel.
Aquila is your teacher in Dragon Quest 9.
You should get dragon quest 9. no doubt
Once a character reaches Lv99 in any vocation, he or she can be revocated back to Lv1 in that profession, by Jack of Alltrades, at Alltrades Abbey.
No. However, when you defeat a grotto boss, the quality of the map you get is partly dependent on the highest level you have in any vocation.
