Airport Express/Router Connection - Help Needed!

Question

I was given an Airport Express for Christmas to use to beam my iTunes from my iMac to a pair of powered speakers in a different room. I was using the AE in conjunction with a Netgear wireless router.
It was a pig to set up but now I wish to change everything and I might need help.
I want to connect my router to the iMac by ethernet cable - the 2 bits of equipment are only 2 feet apart! Thus the AE will be the only piece of kit connected wirelessly to the router.
I would like to delete the present connection of AE to router and start again.
Is there anything I need to know about changing my router to Mac connection from wireless to wired and reinstalling my wireless connection from router to AE?
