Wow definitely needs to be a sticky! Only things I'd like to comment on would be about insurance and coolant. I find insurance being a very touchy subject and to even try and achieve some sort of coverage at the track may be risky. I just can't see you coming out on top when mentioning feats of speed to insurance companies. If it has been done before, then sure its worth a mention but I would be leary. Also, regarding the coolant recommendation, correct me if I'm wrong but isn't it a requirement of ALL track day providers to remove the coolant and have water? If not, I'm sure its HIGHLY recommended.
Great note about visualizing the track prior to going, I'm pretty confident I've watched every TMP video on youtube and it helped immensely. It was all new to actually be on the track but knowing the layout helped greatly in focusing on other things. As Keith Code mentions you only have so much attention to spend on things ($10) and if your spending $9 on learning the track, its hard to work on other things.
