It looks like you've got a lot of the big ones already covered, or on tap. In "using PsTools" I might suggest covering PSLoggedOn. It's probably more use to enterprise admins than at-home geeks, but also probably the command-line SysInternals tool I personally use the most.
Another one of interest might be Desktops - the virtual desktop manager. Haven't tried it myself (the idea of multiple desktops never really caught on with me) but I'm sure there's others who would be interested.
ShellRunAs is cool, but deprecated with Shift+Right-Click in Win7 (and maybe Vista).
I'm not sure what the purpose of PsShutdown is, since Windows already has a built-in shutdown utility usable via CLI or GUI - and it works across the network as well. Maybe it is from a time before that was part of the standard build.
