Help me: Beginner's guide to xbee & lilypad & Max

I have an arduino lilypad, the xbee pad (with an xbee pro on it), accelerometer pad, power supply, xbee explorer, and i'm trying to get it all to talk to Max/MSP. I can get info into max if I plug the lilypad straight into the computer. Now i'm trying to get accelerometer data from my wrist to communicate wirelessly using the xbees. I have multiples of all of these items.

1)How can I accomplish this?
2)Can I recieve data from multiple lilypads with xbees to one computer? or do I need multiple recievers with multiple computers?

P.S. I'm on a mac.

3)What programs do I need to program these?
4)Do you have sample code?
