Sounds like a pretty standard wedding. Nothing ever goes 100% on-schedule according to plan, and you have to be prepared to adapt. You can't expect other people to accommodate you, either - for instance, the door blocking your OCF, as soon as you saw it might have been a problem you should have bolted over there to change it. Move the light since you can't move the door.
I would pin this 95% on you and 5% on him. A single Facebook message is inadequate at best. If he left his computer on with Facebook open in the background, and walked away, Facebook would still say the message had been read.
I understand Nathan, but as I mentioned, that was just one example. I had asked several important questions via email on August 20th (indoor, outdoor, first look, etc.) that were not answered until September 23rd after more emails, texts, and phone calls. But I understand where you are coming from. A facebook message was inadequate at best.
With regards to the OCF, once I saw it was happening I did shout out to the groomsman "Hey! You're blocking my light!" and he asked "What should I do?" and I said "Close the door!" By that time, my wife had already grabbed it and was holding it over everyone. There was no need to run over and move it because it was already being taken care of 
Bryan - YES! Thank you! You guys that do this full time deserve to be commended. I've always gone to weddings and never paid much thought to the photographer (until recently). I was on my feet from 3:15 to 11, no dinner, a couple drinks of water, and 1350 shutter snaps. Now if I just shot more weddings I wouldn't have to exercise!
BTW, here are a few shots.
