I have an answer to you question #3:
I made this same mistake few years back ... :)
I had configured a router that would use the fastethernet interface to route
out and using the command
ip route 0.0.0.0 0.0.0.0 fastethernet 0/0
It didn't work!!!! But,
ip route 0.0.0.0 0.0.0.0 123.45.67.89
worked. Same as it your situation.
Well, we are used to using
ip route 0.0.0.0 0.0.0.0 serial 0/0
and this works. So, why does one command work while not the other????
====================
Answer is serial interface is point to point
and
fastethernet interface is point to multipoint
On a point to point, you only talk to one distant end device.
On a point to multipoint, you are putting the packet on the wire and hope
that another device picks that packet up.
