I'm not sure about MP, but I have enough TP that I never seem to run out, unless I was raised. I don't think houses are available yet, they may only offer Free Company (FC) housing to start. Quickest way to level is prob fates, shout for a party you'll get more exp than doing them solo. I waited till lv. 50 to start crafting. It's best to lvl them all together to at least lv 20 because they start becoming interdependent at lv 16-20. Save you're leves for crafting if you plan on doing any crafting. Pick up mining and Botany first though and lvl them. You can make money selling stuff you gather if you need a break from the game.
