Help with Product Pages

https://firetowerknits.com/ I have 3 issues. 1) When clicking on a product, the image is cut off until you click on a thumbnail. (example: https://firetowerknits.com/?product=brightly-striped-hat-of-orange-and-pink-teen-adult) 2) I'd like my Description and Additional Information section to be directly to the left of the product pictures and the payment information underneath. Is there a way to do this? 3) Can I change the header text size and category counts with the background color?
