I've just defeated (SPOILER) Doctor Cid in Draklor Laboratories and my main party is at levels 36-38. What good places are there to farm experience and Gil where I'm at?

And don't tell me it's easy to get Gil in this game! I become increasingly poor the further I go into it!

Also,

(SPOILER)What on earth is this Venat thing? Is this thing going to get an explanation any time soon? It's really starting to irritate me.

(SPOILER)When will Reddas join my party?
