Using the Arduino Diecimila and Lantronix Module

Hi I am kinda new to the Arduino board. I currently have an Arduino Diecimila and a Lantronix MatchPort b/g pro. I was wondering if anyone had any experience in using these. The posts I found were not much help.

I want to use the matchport to host a web site then use that website to pass values to the arduino board. The arduino will then be using those values to do separate calculations on its own and possibly pass values back to the matchport. The matchport will be connecting to a wireless network and connected to the arduino locally.

If you could provide any help it would be much appreciated.
