Nice diagram Bob
There have been lots of discussion of late as to why only a WAP and perhaps a switch are all that is needed in most cases. I agree.
However, since most consumer wifi devices are, as you say, combination devices with a WAP, switch and router in a box, I thought I would share how I use mine.
I use Netgear WNDR3700 wireless routers. They cost a little under $100 these days.
I like them because they seem to work well. While they are much larger that the apple boxes, I think their size and stand up orientation provides a better wifi signal. I have 2 and never have problems.
On other thing I like is that it easy to turn off the 2.4gHz radio as I like using the 5gHz band which, at this time, is less crowded.
I usually change the network number from the default (often 192.168.1.0) so to not conflict with other gear. I Also change the wifi SSID to something innocuous that does not suggest what the network is used for.
I configure the WAN port (or Internet port) to be DHCP and make sure the firewall is on and set to discard all unsolicited packets from the WAN port. This is often the default configuration.
At shows, I NEVER connect my network to any other network. To do so without knowledge of the foreign network is to invite problems with your network and therefore your show.
However, at home or at the shop, I can simply plug in the WAN port to my internal local network and have easy access to my own computers and easy ability to download updates for my audio gear.
I hope this helps.
