The main thing I heard people talk about was the track condition. Even the guys running DRs were complaining. Another comment was lack of runs on the strip. A few of the autocrossers had to get out of line to attend the mandatory drivers meeting that was "supposed" to start an hour after T-N-T(it was more like 10-15 minutes). There were also gripes about events not starting when they were supposed to. Reading your post, it sounds like there was just a miscommunication with the track staff. That could happen at any event. I've only been to about 5 events at Beech Bend and they were all pretty much on schedule. I do remember the track was in horrible shape at the Cruise-In last year. I don't think they put any VHT down at all.
As for the Z06FEST, from what I hear there was not enough "definites" from the Z06 crowd to make it to Bowling Green last year, so the guys who were promoting it decided to wait. It will definitely happen this year, as they have already booked the museum and the track.
