I've used fixed heights for the navigation and maincolumn, but I would like the footer to be aligned at the bottom of the window and the navigation's and maincolumn's height to be adjusted when resized.
Also, I'd like some suggestions on how to position the copyright information in the bottom of the footer.

Try searching the forums for this problem.
As far as I can remember it can be done with absoulte positioning, but that's a problem if your content is more than one page... the effect most people that ask the question are after is like having a 100% height table, with a small cell at the bottom for the footer; that will sit at the bottom until the content gets too big and then it'll just sit at the bottom of the page. But in CSS, this is very difficult...
