It appears that you have eth0 setup as the card you want to use for your LAN, this is ok you should see it listed that means it appears to be working ok.
Look for adsl-setup it will walk you through the setup of the adsl connection. During the setup say you want it to run on eth1, when you launch adsl-start it will start a ppp0 interface which will use the eth1 card (if you type ifconfig after adsl-start you will see it listed). Perhaps you could check Linuxconf or a Mandrake network config tool to make sure that both cards are installed. Hardrake will also allow you to view which cards were found on the machine.
You may need to get the adsl software from the CD, not sure about Mandrake 8.0, however in the past the package was called rp-pppoe-xxxxx (something like that). so rpm -Uvh /mnt/cdrom/Mandrake/RPMS/rp-pppoe-xxxxx.
I noticed your from Canada, that is what I used to do in order to connect to Sympatico which I assume is your ISP
