Not to discourage you, but your best bet may be to just jump right into things and see which players in your parties you become friendly with.
I implore you to not level your jobs by being a "keyer" and learn about them so when you're at lvl 99, you're not overwhelmed and bewildered by the array of job abilities and spells.
That being said, I'm on Lakshmi and would be willing to give assistance in game as long as I didn't feel it was a waste of my time. (I'm not really this curmudgeon-y, but I want to be really clear).
See you on the server.
You have drg, blu, mnk, nin, war and blm? Can you come bard? Come bard.
