Product Image Item Name- Price fonts are different sizes and I can't find the fix

  1. Prev Listing Next image buttons have what appear to be different color (red and blue) link status borders around them. How do I make them go away?
  2. I want light gray borders around all my product images, but there is a tiny 1x1 pixel image above my first subcategories page (no images) with that same gray border around it. Can I turn off that litte image somehow, since I am not displaying product images at this level?
  3. Why does the body tag have a font size of 62.5% applied? It seems to be affecting other font sizes I want to change
.

Thanks for any help.
