Icons in the main panel in KDE3.5 can be moved around by right clicking on them, this doesn't seem to be available in KDE4, they go where they want and I cannot find out how to order them the way I want. Is this possible? How?
unlock the taskbar/the widgets and in the taskbar cashew? right click and panel preferences, you will have a tool that let you move the icons wherever you want, just move the cursor over the icon you want to move and move it, also you can move all other objevts you have there
"What's a widget?"
have you seen those pretty clocks or those nice trash can or those weather apps in the desktop?
those are widgets, small apps that will stay running in your desktop, there are many widgets like those, if you have seen google widgets, you can add those too in kde4, there is a big list and increasing constantly with variety, rss, weather, clocks, translators and others more
"The left hand few icons stay put, the right hand ones move around mystically, not such a big deal though"
the icons that move around in the right side together with the "i", this is normal, it just shows what apps are running in the system that can have a module there to configure or call actions
