Depending on the drivers on the system, you can specify that a wired connection disables the wifi. I've seen this mostly on Intel drivers, but some Dell cards support this as well I believe. Since I almost never install the full [crappy] software package that comes with wifi drivers, you can look for this setting in Device Manager, under the Properties for the wifi interface.

Yeah, good luck with that. You can see the route metrics by running "route print" (at least under XP), and you can add/delete routes using the "route" command, but I don't know where to set default metrics for new connections. Generally, the wired interface will have a better metric, but I have seen occasions where my browser traffic will prefer the wireless interface, while other non-browser connections remain on the wired link. I generally just kill the wireless when I'm docked.
