I'm about to enable Media Access Control (MAC) Address filtering on my home wireles network and I have a question. I know I need to enter the MAC addresses of the clients on the network as "allowed" -- so that would be any computers like my laptop and my desktop machine.
My question is: Do I need to add the MAC addresses of my printer, my routers, or other devices on teh network to the list of admitted/permitted devices?

Depends on how your network is configured, and your equipment. Some wireless routers have separate filtering for wireless clients and wired clients; in this case you need to allow the MAC addresses of wireless clients in the wireless list and you can take your chances that nobody's going to sneak in and plug some rogue computer into your wired network  . Others have a combined list, in which case you probably do need to allow all of them.
Details help... What routers, what printer, etc.?

Hmmm, well let's see: - iBook G4, wireless
- Power Mac G4 (AGP Graphics), wired
- Belkin 802.11g wireless access point w/ 1 wired port
- Belkin 802.11g wireless router w/ 4 wired ports
- HP LaserJet 1160
- Microsoft Xbox
I have already keyed the MAC addresses of all of those devices into my router. I guess there's no harm in that. I just wonder if MAC address filtering is really only beneficial for the tower, the laptop, and the gaming console, and that the addresses of the router, access point, and printer do not need to be known because filtering for those would have no practical effect.

It depends on how you have the two Belkin boxes plugged into each other, and how Belkin manages MAC address filtering. I'm assuming you have the access point plugged into the wireless router. If the wireless router has separate address lists for wired and wireless, then the printer and access point's addresses shouldn't be an issue.

The router and WAP are not plugged in to each other; I'm connecting them wirelessly and using the WAP as a bridge. The router interface does not appear to distinguish between wired and wireless MACs, so maybe I do need to just put everybody in. No harm, right?
