I though SQL Server 2012 Express Edition was "Released for Production", however when I download it, it still states "RC".
Maybe I don't understand "RC" fully, but I though that was just before the production release?

You are looking for the "Released To Manufacturing" (a/k/a "RTM") version of "Microsoft SQL Server 2012 Express". Microsoft refers to most initial versions of it's products as "RTM". After the initial released, patches are usually referred to as a "Service Pack" ("SP"). When new Service Packs become available there be a download to obtain the patch (in order to update your existing systems) and a pre-patched download (for fresh installations).
Generally speaking, you should either be running the latest SP. If there are no SP versions, then run the RTM. Often, Microsoft support will not help you unless you are running the latest SP.
In the SQL Server world, there is an additional type of patch referred to as a "Cumulative Update". Since CU patches come out much more frequently, as a rule of thumb, you should apply CU only if it addresses a bug that you are actually seeing. Otherwise, you can spend your life doing nothing but patching systems.
TL;DR:
If you google this:
