The one point it really drove home was that, while LSAT and GPA may be the most important parts of your admissions profile, they're also the most easily digested - LSAT is one or maybe two or three numbers, and with GPA they just look at the raw number and then for an upward trend and the diversity/difficulty of courses. The entire remainder of their time is then spent reading your personal statement, LSAT writing sample, resume, letters of recommendation and addenda, and they evaluate how these fit together along with your "numbers." Basically they will spend the majority of the time reviewing these components, so the good news is you do seem to have a fair bit of input into how your numbers are evaluated. Terrible numbers are still terrible, but median numbers can be bumped up in the pile.
I'd recommend going to one of these mock admissions committee things if they're having one local to you. Pretty amusing, and a good chance to meet the deans as well.
Also if any of you drew pictures on your LSAT writing sample... bad move.
