you only need to give the VLAN commands to the port channel, not the individual interface. Commands given to an interface that is part of a port channel will be ignored, until that interface is no longer part of the port channel. The output you have listed looks fine to me. Knowing how things are configured may better help to put things into perspective.
from standard Vlan configuration point of view. ? regards
if a port-channel is in a Vlan do I need to manually-specifically put its ports 
into that Vlan too?
