Hello and

to the forums.
Connecting to your Pc monitor is pretty simple.
What type of monitor do you have?
A VGA cable should be fine. Make sure it is one that fits your XBox 360.
If you only have one port on your monitor you can buy a VGA switch to hop between the two or just pull one cable out each time you want to use the VGA port.

As for connecting to XBox Live it is an ethernet cable you will need.
Hook it up to your modem or router.
A HDMI lead is for video. If you have HDMI connection on your TV or monitor you can connect this way.
