I think I found an answer to your problem. Instead of command-k in the finder, try shift-command-k (or the Go Menu -> Network). This will get you in to the network. Now choose the servers you want and log on to them. Next double click on the icon for the user's directory you want to access, it will show up as an icon on your desktop.
Now control-click on the icon and choose "Make Alias" from the menu. You now have the ability to jump right to that user on the network from the alias.
Do this for each server you wish to access and just keep the aliases for them somewhere on your desktop, or even in a folder together on the desktop.
