I know that for the most part, there are a finite amount of enemies to be found in any given section of the game as you progress, but is there any point in time where enemies will respawn themselves, so that you can get a one-up on your party levels before heading to the next part of the game?

Some areas will respawn enemies if you leave them and then return, say for example, leave a field and eneter a town and then return to the field. But because the game is so linear, there aren't many opportunities to do this...

I haven't touched this game in over a year, but my recollection is that there is NOT a great deal of time allowed for grinding of any kind, so when you DO get it take it. Zoning does seem to respawn enemies and I do recall when back at headquarters I could go into other areas and do a little leveling, but yeah - like Matt said, it's not really built for that.

I haven't really touched the game for awhile either, so I was interested in the information for when I decide to pick it back up again, though my memory of what's where, who's doing what, and how to kick butt is so foggy I may very well have to start over. ><
Well, I say POO to the lack of respawning... POO, I SAY!

It's a damn shame this game wasn't better - the visuals blow my mind and made me a Hyung Tae Kim fan for life for realz, but the game was becoming more of a chore than a joy to play.
