PageSpeed insights and pingdom, need some tips on removing query strings efficiently, and any other advice you might think helpful :)

Anyone have some advice about a quick and easy fix for these page speed optimizations? I'm using SG with WP, I handle the backend stuff myself. My brain is burnt out after developing for many hours, I'm at these final few touches for optimizing delivery.

Thanks in advance!

"Remove query strings from static resources: Resources with a "?" in the URL are not cached by some proxy caching servers. Remove the query string and encode the parameters into the URL for the following resources:"

"Eliminate render-blocking JavaScript and CSS in above-the-fold content"

• "Your page has 5 blocking script resources and 18 blocking CSS resources. This causes a delay in rendering your page. None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML."
