Max it out. I wouldn't max out the first job skills like iron body of endure, it'll just save your pot money by a little. Wouldn't you like to max out power guard and fury instead? Isn't doing more damage and inflicting damage from a monster's attack better than 40 weapon defence which is like 13-14 less damage? Remember, you got 121 skill points from 2nd class to 3rd class. Mastery - 20; FA - 30; Booster - 20; Fury -20; Power Guard - 30; Total - 120 Used points at level 70 + 1 extra skill point. You can do whatever with your 1 extra point. Overall it's your choice; I'm just making a guideline for you XD.
