WordPress Optimization help?

Could I have some help and advice please. I’ve been looking at metrix and google page page speeds to try and improve my site. It seems a few plugins are needed to improve the scores but some are breaking Enfold.

This is my site.

Above the fold by pagespeedpro does the same.

Gzip is enabled but still shows these results.
