I'm a dolt; the problem was that the gnome default keyring got mucked up by
the changed MAC (which you could probably anticipate), and then that's why
NetworkManager stopped working.  I'm not sure exactly what happened, but I
took a backup copy of ~/.gnome2/keyrings/default* and now it's fine again.
Probably you could delete these files and then the nm-applet will make them
again, but I'm lazy.

I still didn't get wicd working, but I never had that working before, so
that's probably a configuration issue, and in any case clearly unrelated to
toying around with my MAC address (since I installed wicd later anyway); I
originally though since NM was also assigning the default IP addresses that
it might be related, but that's because I'm inexperienced.

I'm a little embarassed that the solution was so easy and obvious and I
bothered everyone.  But I did learn some things in the process, so I
appreciate the feedback a lot.  So, as I eventually move to use wicd, the
comments here will be helpful for me.
