There you'll be able to see lists of all the apps on your phone and you can click on each to get to a 'Clear cache' button.
My suggestion- visit the all things root section of the forum here, and root it! When I rooted my phone and installed a custom Rom, I had almost 50MB more of memory than I did before. Just make sure to back up everything on your phone, as it will require a complete reset. I can't speak for everyone, but after I rooted my phone and installed a custom Rom, I was really glad I did, and wouldn't even consider going back.
