Customising GO launcher

[Guest galorin]

I'm using some ideas from http://themedroid.com/2010/11/scrolling-wallpaper-2/ but using a few of my own preferred tweaks, such as Go instead of LauncherPro, just because I like it more, and I didn't like the shortcut idea. So far, everything is almost perfect, with the exception of the graphic for the dock background image. It's either too big or too small, how big should the dock background image be?

My Google-fu is failing me, and if it's already been answered here, I just can't find it... but once I get it up and running, I'll give it a run-down here if people like.
