I have a million ?'s. Please help me out with these as i'm sure i'm not the only person that has them, I hope. Also links to answers would be great. So here we go. (I'm an FFXI vet and I think that might be hindering me a bit here)

1. How exactly do you get adv. jobs? (Smn, Pld, ect.) I've been told that you need to get 1 job to 15 and another to 30 or something to this effect. What are all the combos?

2. Can you rent chocobo's and ride them where you want or is the auto chocobo all you can do until you can unlock your own?

3. Is there a way to tell how close you are to spiritbond on an item? I see a bar next to the item durability bar i am assuming that that is the SB bar but I don't understand how to read it. My items have different colors on that bar.

4. What are the icons on some mobs. I see a blue icon sometimes and red triangle icons. Does this show what mobs link and aggro? If not how do you tell which ones link and aggro?
