Improving Enterprise Application Reliability - ASP.NET/C#

Question

I work with a team of 10 developers in creating an enterprise application built on .NET / C # and SQL Server 2005. The application is mature and large, but there are many opportunities for improvement in terms of reusability, scalability and performance.

I would like to help make the application more reliable and would like to know where I could find suggestions / tips related to ASP.NET and SQL Server. As an example, I helped add Memcache to an application that made the application run faster. I'm not looking only for major improvements - the less they help too. One of the small changes we made was to create a library that encrypts hidden data, making the application more secure (previously, the fields of the hidden input form were not encrypted)

I have not worked with larger applications before, and I lack experience in this area. Any online resources, websites, books, documents, articles that will help me in my searches?

GUI Bloopers 2.0

If you make sure that you are not committing any bloppers, you will make your users a great service. The most interesting section for me concerned perception of speed. Even if you optimize a certain algorithm to be faster, users may still have the feeling that it is slowing down. It really affects how people relate to your application.
