Answer 1

Yes install VNC on her machine.  You can download ChrisControl and remotely install (it called a Push) the VNC server onto her PC if you know her password or she never set one. Just make sure when you do it you use view mode only or you'll take control of her PC and the jig will be up!

Also if your techie enough download ResHacker and remove the icons so she wont see it running in the system tray.

Answer 2

You can get a network sniffer and watch her network packets.  Might be interesting.  You will just see binary codes and some text.  it's pretty boring, but you might see some email if you are lucky!
