After Update: Menu broke, images fuzzy/pixelated

Just updated Highend and it really did a doozy on my site:

http://www.thetreecenter.com

– The main menu now shows all kind of text hovering over the entire page.
– All of the thumbnail images are now super pixelated (it wasn’t like this before)
– The product page image is not the full size. It is smaller than it was before

Attaching screenshots of original homepage.
