I'm using ssh and X for lan remote acces and from work I'm connecting to tightVNCserver running on the plug with tightvnc portable viewer.
If you have windows add to all those the swiss knife putty and connect to the plug with it through ssh, X or VNC tunneling to secure the remote acces.
You can also take the faster NX road but it's not recommended to noobs.
You can find a lot of information in the forum but you can also have a look at this page -->
