AYou should be making more than enough money to pay for new skills, updated armor and weapons, gryphon flights, stupid noncombat pets (hey I love em too!) etc. But keep in mind you are working towards two things when you hit lvl 40:
1. Buying your mount, which is going to cost you 90g
2. Preparing for your first crafting profession, which will take money to level and buy schematics/patterns/recipes/etc.
You cannot enter Phase Two until you have purchased your mount and have like 100g in savings. Trust me on this one.
