I don't have any experience migrating access to a web-based interface, although I have heard of people going straight from access to a web page. MySql is exceptionally easy to migrate. MySQL.com has a program called mysqldump that comes with the standard install of MySQL that allows you to export your database straight to a text file that can be used then with mysqldump to import it on another server. I don't believe the WAMP server comes with the command line tools although they can be downloaded from mysql.com. However, if it has phpMyAdmin, then there is also an export feature with that as well that will generate a .sql file that can be imported to the webserver using phpMyAdmin. One thing to keep in mind though is that I have had very little success mixing and matching these methods: ie, I've never been able to get a mysqldump-created file to work with phpMyAdmin and vice versa.
Good luck!
