In some cases, it really depends on what your ISP has configured.

Thats pretty likely.

Thats not always true. I've got an acatel modem on which I can specify
user name and password lists to use for automatic authentication via
pppoe on ADSL lines

Most pppoe packages have an associated scripting language that let you
script actions to take in response to certain events. You'll need to
read the man page for your pppoe package (assuming your provider users
pppoe..it sounds like they do).

Yep.

Not that I'm aware of, although with the right equipment, you may be
able so set things up so that in the event your router fails, you could
circumvent it and establish a pppoe session with individual clients on
your internal network.
