reinstalling/redoing network

[Paul Cartwright <ale@pcartwright.com>]

I want to redo my network setup, as it seems to be hosed beyond my capacity to 
fix it.
	This is my day-to-day home system, so I'm afraid to delete everything and NOT 
have network access. Last time we talked ( and I hijacked a thread on 
newuser-network) the suggestion was made to remove all GUI networks apps and 
just manipulate the files manually.

here is my current situation( with network up and alive):

I have 1 network card, and my PC is connected to my netgear router ( 
192.168.10.1)

I am running KDE

here are the network packages I have installed:

what is my next step?
if I remove all the packages will it take my network down?
If so, what do I need to add or make sure I have in what files?

thanks,
