Fix weird spacing on product page

[jasminsharp97]

I'm working in the Lorenza theme, and this is my store:

Store: https://66cdcb-86.myshopify.com/

I'm running into a few issues on my product page and in my header:

1. I want the spacing above and below the "add to cart" button to be the same, and there's extra spacing underneath that I can't figure out how to get rid of. I also want to change the color of those divider lines to #B7B1B1 instead of their current black color.

2. I also want to change the letter spacing of the entire menu so there's 1px between every letter.  

3. The final thing I want to do is change the cart icon to a custom svg I have.

Please! How did you fix the spacing issue?
