I'd love to chat further but I am amazingly busy. However, with my Earthlink 
DSL connection the only thing required is to run adsl-setup then adsl-start. 
There is no configuring of ppp as that is all done by rp-pppoe.

One thing strikes me as odd about your setup though. Why did you ifconfig 
10.0.0.1 your NIC? The NIC used to connect to the ADSL modem doesn't need an 
IP. Giving one wont hurt, but it may add to your confusion.

The difference between a router modem and bridge modem can be huge. For a 
bridge, you will need rp-pppoe and you will get an IP from your ISP 
45.231.xxx.xxx etc. etc. 

For a router, your modem will receive an IP. After it connects you run 
dhclient or dhcpcd (dont use slackware) and you will get an address like 
192.168.0.100 with a gateway 192.168.0.1. In the latter setup you should NOT 
use rp-pppoe. A router moded will need you to "log-in" to the modem and set 
up your username password there whereas with a bridge its handled by 
rp-pppoe.

HTH!
