Purchased Template CSS question

[Drachsi]

I bought a template which uses HTML 5 and CSS3. I after a while I got the site to look and feel how I want. The problem is there is just to much code in the css file, I would like to remove all that is not neccesary to speed up loading times. I have Expression Web 4 (Just updated) If you want to see the site it is at drachsi.com
Help, ideas and even better, solutions appreciated.

well, your solution is going to involve learning html, css (and maybe javascript) and coding it yourself instead of using web authoring software.

or you could hire someone else to do it.
