You get 4 leves every 12 hours, real world time. If you want to know when you'll get more leves, type /clock into your chat bar. It will let you know when the leves will reset (and also when you'll get more anima, when the next behest starts, and what time it is in the real world).

You can store up to 99 leve allowances.
2) I have yet to be in an actual party, and I hear that the entire party can do the same levequest as the leader? How do party members do this? and does it use up a Leve allowance for them to do it?
If you're in a party with someone else who starts a leve, you'll automatically be on the same leve as your party member. If you join the party in the middle of a leve, you have to open the aetheryte in your Main Menu, and then you'll be given the option to join the leve of your party leader.

Performing a party member's leve doesn't use up any of your leve allowances. However, you get less of an XP bonus and less of a gil reward at the end of the leve. But the advantage to performing leves in a party is that you can turn up the number of stars you're running the leve on, and complete it faster, which means you'll get a better XP bonus at the end.
