Is there a list of recommended updates/patches for IIS 7.5?
We recently experienced an issue with the IIS worker process using a lot of memory which cause the application not to function correctly.

It is recommended that you keep your servers, IIS, and the .Net frameworks updated with the monthly patches that Microsoft releases.
In the many years that I have been using IIS, I have not experienced any issues with IIS memory itself. High memory usage that you are describing has always been due to the application itself.
Here's a great, detailed post on how to troubleshoot memory issues that should help get you started in understanding this better.
