Dual Screen HELP

Hi
Im try to sort out a dual screen from a docking sation for a travelmate 5735. I need to do it so my boss can just plug in the dock and then out off the two dual screens. The trouble im having is finding and knowing if a system such as the matrox dualhead2go will work with the laptop but also all the stuff to make it work and as its my boss i need to get it right haha

so i would really appreciate some guidances on this matter as i have read alot about many different ways but as im not a computer genuis im still have a lot of truoble.

Kind Regards
