I presume you actually meant the *wireless connection stll doesn't work".

We really need the full output of ifconfig. What does 'ifconfig wlan0' 
        give?

*This looks fine!* ifconfig should show Up addresses for BOTH 
interfaces. If it does not, then we have one sort of problem. If it 
does, but you cannot connect wirelessly, then it means another sort of 
problem, probably related to security or encryption.

Yes. It is actually simpler to download the 2 packages from 
wicd.sourceforge.net, and make && make install. That avoids the sort of 
conflicts you got.

Please post 'ifconfig wlan0'. Use system-config-network to configure the 
wireless interface. If you get wicd installed, then do a 'chkconfig wicd 
on' and 'service wicd start', then use the desktop icon for wicd-client, 
and configure the wireless card there too.
It usually helps to start by turning OFF all wireless security on the 
router and on the laptop, while you get the rest of it working, then add 
MAC filtering and WPA keys etc. last.

Sounds like you are actually quite close. Once wired is working, the 
universe of points of screwup gets a lot smaller!
