Once you progress through main story quest you'll get recommended quest feature from lv10 (after finishing the mainstory lv10 and unlocking the Inn and rest of the goodies)
This will show you all the quests available currently in that area you're in, at default it only loads when you login, but you can go through config and have this display show up everytime you zone to a new area, and it will update when you switch class/job. It will also display all the mobs listed for that current class in hunters log as well, so that should help you progress through your levels
