I don't think there is a way to make it fit perfectly to the page with Theme Designer. Also that's kind of a bad idea because it would look weird for some people. For example, if one person has a widescreen monitor, another person has a normal 4:3 aspect ratio, and someone else has an iPad -- the theme would look distorted for some of them if it was auto resized to fit the screen.

About promoting your wiki, there's a list of ideas at Help:Attracting contributors. Some good ideas are setting up Facebook and Twitter feeds. You can also request help from the Community Development Team to optimize your main page which is the first thing visitors to your wiki see. And keep writing articles and adding links to pages on your wiki to build up content and get better search rankings.

Also, if you need additional help, don't forget to check the help pages at Help:Contents. If you have questions, I'd recommend joining the chat room or use the support forum. You can leave messages on my wall if you want, but I think you'd get a better and faster response in those other places.
