I'm also trying to install PHPMyAdmin. I'll need some help with that.
The problem with MySQL is that when I install it, and get to the end where I press 'Execute', the last one fails. It's just... Do I install it in the same directory as my wwwroot? Or in the previous directory? Or some other one? I'm just asking, how do I configure it to where it knows to interact with my IIS server? Or will I need something a little more different like Oracle?
Well, I can't help you with this, but I do recommend that you use Apache instead of IIS.MySQL has always worked for me with Apache.
I also reccomend Apache.
I have no experience with IIS but I'd assume it's similar to Apache.
Just install MySQL on your server, it doesn't have to be in your website root. PHPMyAdmin should probably be there though.
Sorry I can't be of much help. Try googling IIS+mysql+install
