1. As you are completing the Bestiary, since you will eventually have to do it anyways. Or if you don't want to complete it or already have, a good place is the Overlooking Eternity area in the Nabreus Deadlands, since about 50+ Dead Bones spawn there per entry it seems.

2. The top part of the License Board is somewhat more important than the bottom part, since you probably care that someone has Augments such as Magick Lore, Battle Lore, HP +500, and Swiftness more than you would about whether or not they could equip all the weapons and armor in the game, some of which are ridiculously hard/impossible to get anyways. So you once you get all the Licenses for all the desired weapons and armor you want to equip on the character, you should just complete the top part and just fill the bottom half when you have nothing better to spend the LP on.

By the way, why would you want to level so early? Do you want to ruin the whole game for yourself?
