I seem to be one of the only one on this thread crazy enough to say no to Harvard. I'll be attending Penn CAMB in the fall  

Accepted to Columbia University - Biomedical Informatics =)

Dear [whoever], I recently had a paper accepted for publication with [journal], and wonder if it would be possible to pass this update along to the admissions committee. I attach here my updated CV, which shows the full details concerning this publication. Thank you, and I look forward to hearing from you soon, -me. 
(In other words, no need to attach the paper, just tell them briefly that the paper has been accepted and send them an updated CV. If you didn't submit a CV, add instead the full details of the paper to the email.)

Unless you were given specific instructions to NOT email the professors, it should not hurt for you to email them. The worst that could happen is that they ignore your email (and don't feel bad if this happens since many profs won't write back if the only thing the email would say is "cool, see you soon!").
I would just write something like, "Dear Prof X, I will be visiting Awesome University during the Feb 16-17 interview weekend. I'm very interested in your work on XYZ and I have let [person**] know that I would love a meeting with you during my visit. I hope to see you next month!"
(** the name of the person that emailed you to ask for the list of names!)
Some notes:
- Specify the specific dates, as some programs have more than one meeting date
- Specify that you already let [person] know that you want to meet, so that it's clear that you aren't asking to schedule a special meeting with them
- Don't ask for anything specific! They will be very busy and usually these visits are all scheduled by the same person (or a small group of people) and not the faculty themselves, so coordinating anything outside of official channels can lead to confusion
Why I think it's good to do this:
- It shows enthusiasm and interest (and of course, only do this if you are genuinely interested, don't just do this for every single person). I would only send an email like this to one or two professors at each school that you are really really interested in meeting
- If the prof will be away that week, they will probably let you know. This will also help you because you don't need to feel like they were not interested in you if you don't end up getting a meeting with them. If they say they are away, maybe they will offer to call you or Skype you.
- Sometimes profs have more requests than they have time slots for. In this case, the meeting coordinator may ask the prof to choose who to meet with. Establishing this contact with the profs you're really interested in might make them choose you. (Corollary: This is why I don't recommend emailing 5 or 6 profs like this, since it won't help prioritize your meetings).

I'm fairly confident it's based on the interview alone 
I really don't see an adcom being like "Oh, he was great on paper and an amazing interviewer, but his GRE could have been better" haha 

Generally you are awarded interviews because they (industry, academia, w/e you are applying for) looked at your application package and said "this is good, lets talk to them". I doubt they would return to the application package to make the decision when they went through the time and effort to interview you. It would negate the entire purpose of the interview. 

You can email the program coordinator. I was also feeling the same thing when I don't receive any emails from schools. But when I emailed the program coordinators, some of them are still evaluating my application and will let me know the result. So there is still hope! :-)

I think it depends on the department. For example, last year MIT biology sent out all their interview invites in one day (at least from what we can see in the posted results) and then rejections six days later, whereas MIT BE sent them out slowly over the course of a month. D:

Just a warning for everybody, if you don't hear from your programs that you've received interview invites from it may he a good idea to follow up with them. I am going to a visit this weekend and had heard nothing from them except an email to invite me and one to organize my flight. Yesterday i recieved a few, somewhat frantic, emails saying that i needed to fill out a survey and give a bunch of information ASAP and that i was supposed to give back in December. Turns out I was not on their email list for recruits and had been missing all of their messages. Luckily I got it all sorted out and I am set but I would recommend emailing the department administrator in charge of organizing the event if you have heard nothing a week or two before the visit.

Maximize all the recommendation letters you can have. If the program says until 5 recommendations. Just do it!
