I trying to capture what Vlan certain ports are configured for on my switch. Can wireshark do this? If so how do I set it up?

I would go for the password recovery procedure as that will give you 100% certainty. If you want to deduct the vlan configuration of the switch you might be in luck by the packets it's sending.

You might be able to capture VLAN tags but only if you capture on a switch trunk port by introducing a hub/tap, or by mirroring it to the analyzer port including the VLAN tags (which otherwise might be stripped).
On the other hand: if you want to have a list of which ports are configured with which VLANs you should dump a switch port statistic on the switch itself.
