My suggestion for your project are
1. U can develop this project completely with perl.
2. U can use apache as web server.
3. Use mod_perl for better performance
4. Use mysql which one the best opensource database.
5. Most important thing for this project is html template handling which can be done efficiently using HTML::Template
6. Still Template handling can be done with help of these modules
7. With all of these stuffs go for MVC architecture which looks good
8. And u also have perl monks to clear ur doubts when ever u struggle at any point
