BeagleboardXM Main expansion Header connector / mate cable / pins

Does anyone know how I would go about figure how to find the proper
connector to connect to the main expansion header in order:

1. To connect a ribbon/twisted pairs cable

2. To expose the pings to connect individual wires to.

thanks,

Which board are you referring to, BeagleBoard or BeagleBoard-xM?
Which connectors are you referring to, the LCD or the expansion headerS?
What is your specific application?
