For dialling automatically I would use ppp on demand. All you have to do 
is pass the demand and persistent options to pppd. If you also set the 
onboot parameter, you will not have to do anything. Just boot the 
computer, and if a program requires internet access, pppd will take care 
of dialling and connecting.

I also run an ip-up.local which I've symlinked to a firewall script so 
when the ppp connection is established, it runs the firewall script 
(which in turn sets up the firewall according to the external ip address 
the connection now holds).

Run's beautiful - no maintenance required.
