I agree the order is not critical...a couple of more points...
Do not forget about interface range configuration mode. This allows you
to apply a configuration to multiple interfaces at the same time.
Also, I am always scared of breaking the network, so I ensure I shutdown
interfaces on one side of the link before the EtherChannel formation.
You do not want one side set to EtherChannel (ON mode) and the other
side not with both sides active, for example.
The interfaces you want to EtherChannel need to be pretty much "twins"
in their configuration. By this I mean things like same duplex and
speed, same trunk encap, same allowed VLANs, etc.

I do not think the order of the configuration will really matter ,
however having the etherchannel first will make sense so you can
configure the trunk config under the port channel ( instead of doing it
more than once )
you can have the etherchannel in access or trunk mode and it works
both ways , in some situations some cutomers prefer to have the
etherchannel connections part of single vlan (access mode ) for
performance issues so the link does not have to carry traffic of
multiple Vlans

Guys,
1) I tried it both ways and it worked. I dont think it matters, so far
you configure it in the right way.
2) I am not sure why you would want to configure an etherchannel
between two switches and make it an access port? Not a routed port?
Please would there be any situation when you would configure a link
between 2 switches and not make it either a trunk or a routed link?
Thanks
