Notes:

When I'm zoomed in and pushed for time, I don't always catch everything.  The proper VirtualBox kernel modules I should install are in fact virtualbox-ose-guest-modules-2.6.24-16-generic as Howefield said.

Although I used the ccsm command to launch CompizConfig Settings Manager in Ubuntu Hardy Heron, I found it also added "Advanced Desktop Effect Settings" to the System->Preferences menu; so you can just click that launcher to bring up ccsm.
