Clean up .js and .css, optimize page load order - repost 2

I have a new homepage currently in development for a client. The page has a header slider load issues on initial page load, which were not there before new menu code was implemented. An audit shows a lot of places the page can be optimized, so looking for that optimization of css/js and load order in order to make the page run better, and load smoothly. This is a Responsive site, so please keep that in mind. This part of the development is not quite complete, but need to clean it up before going any further.

Here is the link to the homepage files to have a look before you bid to see if you can do anything: [login to view URL]
