Adding caching will always add complexity. This it true regardless of the language/platform you use, including ASP.NET.

Yes, adding caching in the right places will help performance. Adding too much will degrade performance... it is a fine balance.

I don't know about easier, but it is very easy to use the built in cache in ASP.NET - there are many ways to do it. Read the MSDN overview, here.
