Arial Rounded MT, with its color sampled from the button edge. I've found that the trick to making consistent buttons in Photoshop is to make the basic button without text on one layer, then make a new layer for the text for each button. That way all the buttons can live in one source file. The pages are pretty straightforward, HTML-wise. I don't use them in mine.
Tables can control page layout adequately and work on almost all browsers now.
