Google PageSpeed Issues - "Render-blocking Javascript and CSS"

Hi

I'm getting some issues with Google's PageSpeed Insights, and I'm not sure how I would go about correcting them. It's giving me some red flags, stating that I should:

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

Remove render-blocking JavaScript:

1. /jquery.js
2. /jquery-migrate.min.js
3. query.themepunch.tools.min.js
4. themepunch.revolution.min.js

Optimize CSS Delivery of the following:

01. contact-form-7/includes/css/styles.css
02. themes/betheme-child/style.css
03. themes/betheme/css/base.css
04. betheme/css/buttons.css
05. betheme/fonts/mfn-icons.css
06. betheme/css/grid.css
07. betheme/css/layout.css
08. betheme/css/shortcodes.css
09. betheme/css/variables.css
10. betheme/css/style-simple.css
11. animations/animations.min.css
12. assets/ui/jquery.ui.all.css
13. prettyPhoto/prettyPhoto.css
14. betheme/css/responsive-1240.css
15. betheme/css/responsive.css
16 - 19. fonts.googleapis.com/css?family=Roboto , PT Serif, Lato, Patua One
20. betheme/css/custom.css
21. betheme-child/style.css

It's saying my website load time should experience a significant speed increase if I fix this issue, so how would I go about handling this?

Thank you for looking into this, and for any help or advice you're able to provide.
