Tournies....I can't speak much on these as I have only been in a couple maybe. I know that Quo puts a lot of thought and time into them. The last King of the Hill event went well I thought. Quo did an excellent job of planning this and I thought the few of us hosting rooms that night did a good job of keep the rooms moving. The Vegas tourney that is going on seems planned out well by Thornes and is moving along nicely too.
As for FNFF games I have been volunteering to host/setup the last few weeks, I didn't think any of them were too unorganized. For me FNFF is just about getting a group of us together to just hang out and game. So with that in mind I don't fire up the next game right after a match finishes and I also try to check with everyone to see if we want to keep playing the same game type or mix it up.
I think the chaoticness that you are talking about is due to there being 10-15+ people in a room at once. With that many people there is going to be some confusion with just a few people talking at once.
Prophet send me a pm or give me a call (Pickle has my cell #) so you can tell me what you think will help make things run smoother
