Unfortunately, I never could find a good practical overview of using OLSR.
Maybe I can answer some of your questions, though.

I've only ever used OLSR with a single radio. I suppose you could use two
if you wanted a node to route between 802.11a and 802.11g, for example -
a radio per band.

Assuming you mean best path to the Internet: you can have your 'backhaul'
node advertise an HNA route for that, or use the dyn_gw plugin to have the
routing daemon automatically advertise the default route if one is available.

It will depend on your wireless hardware, but eg.:
iface wlan0 inet static
address 192.168.0.1
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
wireless_mode ad-hoc
wireless_essid mesh
wireless_channel 6

The base package is 324KiB on-disk installed, the plugins 209KiB. In virtual
memory, my quiet little olsrd running on my notebook is using just a hair
under 2MiB.

I haven't had an opportunity to test with a significant multi-hop network,
so I can't provide any information here.

I believe the backports I did for sarge should work on voyage:
deb http://cornerstone.personaltelco.net/debian ptp sarge
I'd be interested to hear the results. Currently, these packages are
0.4.9, while the latest version is 0.4.10; I hope to have them updated
soon.

I'm not sure what you mean by this - could you elaborate?
