Q: Is this article still valid?
Airport Utility does not look like this anymore, and I don't see the "Share a Public IP Address" option anywhere.

If the Time Capsule was functioning normally before you tried to add the Express devices....you should not have had to make any configuration changes at all on the Time Capsule.
Did you make any changes to the Time Capsule? If yes, you need to reverse those changes so that the Time Capsule is setup to operate correctly as a stand alone device....as it was originally configured.
Then my advice would be to temporarily disconnect the Ethernet hub/switch from the network.
Reset the Express and connect it directly to an Ethernet port on the Time Capsule and try the configuration that way.
If it works, you know that you have an issue on your network somewhere.
If it doesn't, I'm out of ideas. I've configured dozens of AirPorts this way without an issue. Just set up 8 AirPort Extremes at my grandson's school this week using a 16-port Ethernet switch, etc and hundreds of feet of Ethernet cabling. Works perfectly.
