It is a good router for light use as long as it's running DD-WRT and not the watered down Linksys firmware.
Use a separate gigabit switch for all your wired devices and link it to a port on the router. You'll get much faster local file transfer speeds (good for LAN streaming), and you'll take some of the load off the router as well.
Positioning of the router is important for wireless to work properly. Don't put it near anything that emits RF noise, such as a microwave, TV, wireless telephone, florescent tubes, or even the computer. They emit a bubble of RF noise, so all it can hear is the noise not other WiFi devices. The router needs about 3 feet of space between it and noisy electronics.
Also remember that WiFi acts like a big slow hub no matter if it's a,b,g, or n. The slowest device on the wireless will drag everything else down with it, and the more devices you have the slower everything will work. For best results, hardwire everything you can into a gig switch.
The WRT54g's internal network ports can only do 100baseT Ethernet, which isn't very fast for local traffic but is 10x faster than most Internet connections and about twice as fast as 802.11g. Unless you have a 100 meg synchronous fiber Internet connection at home, your bottleneck is the modem, not the router.

What can you do with them?
Practically anything. With a new firmware (DD-WRT, Tomato, etc), it can do things expensive enterprise APs can do (although a bit slower). Run newer, more secure wireless encryption. Add an SD card slot and use it as a basic static web and file server. Some versions can be modded with USB ports. Use them as the brains for a robot. Make it a WiFi repeater. Separate a LAN port and hook up a PC to use as a server that's accessible over the Internet. Throw bigger antennas on and crank up the power until it almost cooks itself. Anything!
