I would suggest that the log from ssh -vvv will probably be more useful to you, been a while since I looked at SSH in a packet capture but I suspect that the packets will all be very generic (i.e. there won't be any explicit notation of WHAT a particular packet is WRT the SSH protocol). You should be able to use the timestamps from the log to associate the packets with each step and between the two you should get a pretty good idea of what's going on.
