Kevin on "[Theme: Virtue] Edit mobile layout"

Hello, I would like to make several changes to the mobile layout of the Virtue theme, and I need some help. I tried some suggestions in the forum, but none worked. My website is: http://www.twofoldshop.com

1) My logo/header size is based on the desktop version of the website, where the logo is centered on a long white rectangular background. In mobile, this entire rectangle shrinks, so the logo is now extremely small. How do I enlarge the logo on mobile site?

2) How can I shrink the white space on both sides of my mobile site, so that content appears larger/fills up the phone display?

3) My desktop site currently uses a 4 column footer. On the mobile site, the footer appears vertically stacked. How can I change the mobile version footer into a 2 by 2 table? (Please see Bando.com's footer as an example)
