Assuming that your dsl modem is plugged into eth0, then eth0 is used
only as a physical connection to the modem. Its not an IP layer
connection, so eth0 does not get or need an IP address. pppoe will just
stick the ppp packets on the wire for the modem to receive. The IP layer
is encapsulated in the ppp packets.

This looks like the problem. You need your default route to be going to
the ppp interface, but its currently going to eth0. You can ping the
remote end of the link because there should be a direct route to that IP
address. Anything else is going via eth0, which is not your IP layer
interface to the internet.
To fix this, put the line 'defaultroute' in /etc/ppp/peers/dsl-provider.

No, it wont be a problem. You can get rid of the error message by adding
'noproxyarp' to /etc/ppp/peers/dsl-provider.
