About GP, I found the Q/A:

0:52:50
Q: With the level cap being increased, I believe the maximum amount of GP we can have will increase. Will the speed in which GP recovers increase?
A: The speed won't change; however there is a new trait which will increase the speed for GP recovery. Players will be able to obtain this trait through the class quest series, so make sure to do them!

As an additional note, players will only learn one action for their job/class through quests. These actions are received as a reward for completing the job/class quest series, so until then, the story will be the key element for these quests. For Disciples of War and Magic, I believe you can complete all the job quests at one time when you hit level 70; however, for Disciples of the Land and Hand, the story is directly tied into the gathering/crafting, so please complete them in order.
