Adding wireless router to wired setup

[cosjobs]

I have ordered the D-Link DI-713P Wireless Router & Print Server and DLink DWL650 wireless PC card.. I currently have a sppedstream wired router and print server. Should I daisy chain the D-Link and leave the D-Link's printer and cable connection unplugged? Should I just remove the speedstream and replace with this? or daisy chain the speed stream to the d-link and unplug the cable and printer from the speedstream?
Everything works great now and I want a painless transition.

I see now that this should have been in the tech support area. Since I do not know how to move it I am going to re-post there.
