Maybe I can make my first contribution to the forum!
Over the last 2 years I have produced about 20 commercial websites, almost all are CSS-P and standards compliant. But I will use tables where there is not an alternative relaibale coding solution
I decided some time ago to abandon floating left /right columns or using other tricks and hacks. Instead I absolutly position my col’s and now use the excellent javascript from project Seven "A graceful Javascript alternative to "Faux Columns"
Why did I abandon using floating columns? - The primary reason for me was that having put a lot of time and effort into producing a really nice, clean, standards based design for the client I found I always wanted to clear a float somewhere in the main content (where an image was used) and of course, that meant clearing my left / right cols that were floated also. I have used Absolutely positioned columns for over a year now and find this method suits me best and is very cross-browser reliable (Oh, and I have not had a customer complaint from anyone who may not have javascript enabled) I always try to keep the footer text centred so in the event javascript was not on a users PC, they would not see the footer sitting below the content, but only the left and right nav overlapping the sides, where there is no text positioned in the footer.
This approach avoids the needs for single coloured tiled background images but still allows for easy coloring of the columns with just a line of CSS.
