OK here we go - I now understand (I'm 99% sure) where you are and what's going on - details below

Good - having said that, the ISO button should still function if you choose to use it - it should not be disabled.

OK - this is important and, I think, the route of your issue. Pressing the ISO button and moving the sub-command dial toggles the camera between auto iso being on and off.

Correct - the dials (or if you choose not to use easy iso, the iso button in combination with the dials) allow you to change base ISO at any time without going into the menu!
>Does this seem "correct", or should I go visit Fort >Worth Camera with my D600?
Yes, all is working as you expect. All you need remember is that any time you alter the base ISO, it will apply whether auto iso is enabled or not - and it will remain at that setting unless you choose to change it
As I said before, if you do want to have a default base iso, then you can program one of the U modes to it (e.g. iso 100) and every time you switch to that mode from another it will reset the base iso for you.
