Apart from the hit to your reputation you probably took, I don't think there should be any lasting repercussions. Dunno though, I would probably just restart, just to be on the safe side. I would rather replay 15 minutes or so than get most of the way through the game then find out that I hosed myself somehow (however unlike that occurrence might be).

EDIT: Oh, you have a save right before anyway. Just reload. I don't think it is a big deal either way, but you might as well. I seem to recall that there is a bug with getting a too low reputation, and then having Flaming Fist guys auto-attack you even after you have repaired your reputation. I doubt it would affect you for this, but if you ever want to go back to Candlekeep again, you might want to make sure people don't all want to kill you over some silly bug. I am probably over-reacting, but it is such a small thing to reload in this case.
