A) I want to eliminate the blank strip of the header so that the logo part is flush or almost flush with the top of the screen. I played with #navMainWrapper in stylesheet.css and that accomplished the objective in IE, but not FF. So I guess that wasn't the right place...
Make the background in the navMainWrapper transparent. Be sure to do this for each of the ie specific stylesheets also.

B) I'd also like the footer to match the rest of the page, but do not need all the links there since everything in the left Info box is enough for me. Instead, I wish to add some logos to the footer, like from PayPal, eBay, etc.
I used the footer menu module for this. You can download the module to see which files need to be deleted:
