Hi Mike, please see inline below:

We recently upgraded our Nexus 3548 from version 6.0(2)A1(1d) to
version 7.0(3)I7(3). We can get in from one of the trunk ports
feeding the switch, but there is no traffic passing through to other ports.
I'm not fully versed on the process as I wasn't the one doing it,
just putting in keyboard time looking for resolutions.
1) Cisco doesn't seem to list any documentation for NX-OS 7 on the
3548, yet 7 is the only available software download on their support
site. Some of the links take me to the 3600. No idea if that's correct.
N3548 is integrated into the "Nexus 3000" doc set for 7.x. The 7.x
train is now a converged software release train with a single "nxos"
image for all n9k and n3k, including 3548. One exception is the 3600
series (broadcom jericho+ based), the plan is to integrate that
platform later this year. Definitely don't use the 3600 docs for 3548.
The image management and boot model is a bit different in 7.x, there
is no kickstart for example just one 'nxos' image. The process of
converting/upgrading from 6.x to 7.x can be a bit tricky, if not
performed according to the documentation here:
https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/upgrade/7_x/b_Cisco_Nexus_3500_Series_NX-OS_Software_Upgrade_and_Downgrade_Guide_Release_7x/b_Cisco_Nexus_3500_Series_NX-OS_Software_Upgrade_and_Downgrade_Guide_Release_7x_chapter_010.html
For one thing you mentioned you went from 6.0(2)A1(1d) to version
7.0(3)I7(3). Not sure how you did that, but the doc above does state
"An upgrade to Cisco NX-OS Release 7.0(3)I7(2) is supported only from
Cisco NX-OS Release 6.0(2)A8(7b) or higher releases."
In any case, suggest you engage TAC to help recover this switch if
you have not done so already.
2) It looks like along the way, we got a vdc section added to our
config, but the only instance of vdc I can find applies to 7000
series switches. Is that supposed to be there? Should I just follow
the 7000's config for VDCs?
This is expected, all nexus in 7.x will have a 'default VDC' config
section. Only n7k allows you to configure additional VDCs. There
shouldn't be much if any config modification required in the VDC config.
Hope that helps,
Tim
