Default max-paths is 4 for all except BGP, (which is 1) so command is not
needed.
If IP route outputs two destinations, the load balancing is taking place.
Usually, CEF will do per destination load balancing.
Setting on the interface defines the method and can be per packet (depends
on platform)
for information about CEF tables, use:
"show ip cef 155.1.146.0 internal"
So, to be exact and answer your questions:
1. Depends on the method, per packet or per destination. Packets are load
balanced
2. Not required.
