here is a link that i followed http://ffxiv.gamerescape.com/wiki/Main_Page
on the left side there in the navigation pane you will find Storyline & Battles. Follow those for the story, side, class quests. As for the rest just go out and kill the low level mobs that around outside the city. After you rank up to about 5 or 8(should be fairly quick) join a "behest" these are issued every half-hour at camps by Battlewardens.

Once you have your inv almost full either start crafting with the items you have or sell them for gil. This is a site I use for crafting recipes http://ffxiv.yg.com/recipes here just hover your mouse over the database (under browse) and weave you way to the crafting classes to find recipes that you could do for that rank and class.

Around r20 you might want to join a linkshell (or LS).
