You're very limited with what you can do with css and xhtml on Wordpress.com. You can't write your own page templates or make siginificant changes to .com themes.

What you're probably thinking about is self-hosting Wordpress, and if you do that, you can do whatever you want with themes, css and xhtml. See Main Page « WordPress Codex and Hosting WordPress « WordPress Codex.

Wordpress.com only let's you edit CSS of their pre-installed themes. Actual theme files cannot be edited, and also you cannot install just any theme you want. You will need to self host your own Wordpress install to customize and add themes in the manner that you are hoping to.

Since you can only edit the CSS on Wordpress.com, you might try a background image. You can upload an image into the media section and then, using CSS, format the header area to the height and width that you want and place a background image into the header. And then if you want to get rid of all of the text, you could use something like this on the header to push all of the text off the page:

text-align:left;
text-indent:-5000px;
