Hey Damon,
You'll want to look at a couple things:
1) Optimizing images
2) Calling on smaller images from Shopify
3) Moving any javascript files that you can into the footer of your page. You have quite a bit of stuff that is loaded before your page can begin rendering which will hurt you in all these pagespeed tests.
I'd wager that those three items will present a pretty nice jump in your score(s).
