Well the best advice is to learn how to access readily available knowledge on your own. There isn't always someone to answer your questions on various things, and it doesn't hurt to do a bit of leg work to progress. I feel that researching many things in this game gives you a better grasp and makes you an overall better player.
My personal favorite site is
http://wiki.ffxiclopedia.org/Main_Page
They have a lot of good information available to you.
Other sites to research are:

Most times when asking questions and such (especially on forums and in the game) people will expect you to have the most basic knowledge of the quest/mission/item et cetera that is available. Then questions about things in the game are generally about tweaking gear setups, strategies for quest/missions and the like.
