Steven,

This page shows that now your website has 93% of cache static which is pretty good. Non-cached files are from google fonts apis and others.

If you'd like to test yourself make sure you do it in at least 3 tests to check for cacheability and don't use Firefox as the user-agent as it combines axd files with css an js making their full optimization checklist worthless. I used Chrome user-aget and the results are as above.

Hope that'll let you sleep peacefully. :)
