vBulletin runs on IIS seamlessly. You can also run your ASP applications as well, as PHP is separate and doesn't interfere.

phpMyAdmin is a nice tool to do lazy basic admin, but it's lousy if you're trying to dump a large database that takes more time than the php max execution time setting.

best option is to do it by hand.

1. get SSH access to your server.
2. login via SSH
3. backup your entire public_html folder (assuming you're on cPanel already)
# tar -cvf backup.tar /home/username/public_html

4. dump your database and tar it up
# mysqldump -Uusername -Ppassword database_name > somefile.sql
# tar -cvf database.tar /path/to/somefile.sql

5. move these two tar files to your public_html folder
6. login to your windows server via RDP
7. open a browser window and browse to the two files and download them to your desktop.
8. unzip the two files to your webroot
9. reimport the .sql file to your database
# mysql -Uusername -Ppassword database_name < somefile.sql
