Dwight,
The 1st problem is probably caused by the idle timeout on the far side. Since it is not doing dialer watch, it will time out and drop the connection. The dialer watch side will then bring it back up immediately. The result is that every timeout interval, you connection will flap. The solution is to set the idle timeout on the far side to 0, thereby disabling it.
As far as demand-circuit and dialer-list, dialer watch doesn't care about interesting traffic, so you do not need dialer-group or dialer-list. When dialer watch goes active, it brings the connection up and keeps it up until there is a route to one of the watched routes through another interface. Dialer-group and dialer-list can still be used, but the effect they have will be to bring up the circuit when dialer watch is not active.
