Okay, guys...I purchased glasses off of the internet this evening. I hope they don't take too long to get here. :)

The website I went to (http://glassyeyes.com) had a measurement guide. I had one of my coworkers meausre my PD for me. :)
Ooops...Glassyeyes is the blog about that.
The site I purchased from was http://goggles4u.com.
Also, (so it's in here), here are the frames I purchased: http://www.goggles4u.com/detail.asp?PID=27605
Nice thing is...frames and all, they cost me $40.
So even if I don't like them, I'm not out a huge amount of money.

Where did you get the measurement for the space between your pupils?
