Typically the drivers for most common network cards are already in the
kernel. So as far as that goes it's just plug and play. Remove the old
card(s), plug the new one(s) in and they should get detected.

You can check this on the console with "/sbin/ifconfig -a".

However, CentOS6 and SL6 have a newer UDev, which keeps a config file
about which NIC has which MAC address. If you remove a NIC and add a
different one, it might get a new ethX identifier assigned. Which makes
things a bit more complicated.

The work around for this is to delete that UDev config file and to reboot:

/bin/rm -f /etc/udev/rules.d/70-persistent-net.rules

Once that's done the new NIC(s) should simply pick up the IP addresses
and network configuration that you had assigned to the old ones.
