How do you remove the text (and just have the icons) for the Right Column in the Windows XP Startbar?

Whenever I look at Windows XP Themes, they are turned off. Here is a sample: http://users.skynet.be/bk265512/BlueCurve/Screenshots/BlueCurveSS.jpg

Also, featured in the above image, the desktop icons are larger then normal size. How is this done?

I'm not sure what you mean by Windows XP themes (I do, but it doesn't really apply here... sorta). But you are probably using a shell program, to stylize your interface.
Heh.... Dangerous Dave.

with some win xp visual styles, the start button is changed. as far as the icon size, i am unsure how it is done, but it could possibly be done using icon packager or some form of icon altering program. if you want to alter the startbar yourself, check out http://wint.virtualplastic.net/ you might have to search around a little, but that site is very useful.

here's a screen of a visual style im using.
