Hi,
For " ip route 0.0.0.0 0.0.0.0 fa0/0" to work proxy arp needs to be enabled on the other end.
This is not recommended as the router arp's for all the traffic hence increasing the size of the arp cache.

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.
