Hi ^^

1 - All of them
2 - Everything is useful but Weaver allows you to make most of your clothes but to be honest for first class/job the story and additional quests should be enough to equip yourself.
3 - At 30 you can do your job quest. Jobs and Class level at same time so just become a BLM at level 30.
4 - No. Click/press button quickly...

Thank you for the quick response. One more thing I'd like to know more about is those Grand Companies? When do I get to join one and which one should I choose? Are there any benefits from being in one etc etc?
