I'm assuming the Airport Utility has a setting to turn off this automatic notification.
You assume correctly. To do so, select your AirPort Extreme within the AirPort Utility, and then, click on Manual Setup. On the Summary panel, click on the amber circle on the Status line, and this should take you to the reason(s) for it being amber. You can then individually select to ignore any warnings.
Another option is to deselect the "Check for updates when opening AirPort Utility" and "Check for updates" options on the AirPort Utility > Preferences panel to disable the AirPort Utility to prompt you for any available updates.
What if anything am I missing by upgrading?
Great question. Typically you would "miss out" any any security or stablility updates ... but you also risk breaking something that already works. Not sure which firmware version updated the 802.11n from "draft" to "final," but you may consider doing the upgrade if this is important to you. The old adage of: If it ain't broke, don't fix, applies here. FWIW, I have had no issues updating the firmware to the currently latest (7.6) on any of my AirPorts (Extreme, Express, or Time Capsule). I don't have the exact equipment list as you, but we are pretty close.

It took a couple reboots, disabling bluetooth, upgrading to Airport 7.6, but now it seems to connect to the Airport reliably and get the Magicjack connecting correctly. Hopefully that settles that. The problem I was running into, was the bluetooth keyboard setup was coming up when I booted my Mac Mini without a keyboard, and blocking my Magicjack software. Only even after disabling that, my Airport connection wasn't always connecting. If I shut down and disconnected the keyboard after shutting down, all was better. I'm not touching it now for awhile.

Ughhhhh...my airport dies on my Mac Mini intermittently still. Any idea how to force the connection stay?
