This screenshot shows my kicker arrangement. I posted it to illustrate how exactly does it look (for the poll about the kicker arrangements).
I have 2 panels at the bottom. The first panel is high enough to have task buttons in 2 rows. It also has Kmenu and Konsole buttons at the left side and system tray and clock at the right edge. The second panel's height is the minimal allowed. It has (left to right):
"Show Desktop" button
"Storage media" applet (to quickly mount/unmount removeable media)
some spare space
Color Picker applet (sometimes it's very handy)
System monitor which shows CPU usage graph
Media Control which controls amaroK (though I rarely use it thanks to multimedia keyboard).
Everything else is rather generic (kde 3.5, lipstik GUI style, nuvole XT icons).
