And I will write in something to continually check actual·position against the desired position and throw a fault if they do not match after half a second or so.· There is an electronic position indicator on the transmission I can use for this.

They have similar articles that explain how linear regulators work (search for "wiki linear regulator").
Companies like National Semiconductor have lots of datasheets and application notes on linear regulators (and switching regulators) that describe in as much detail as you might want just how they work and how you can use them.
It used to be that switching regulators were complex devices. Now there are lots and lots of switching controllers that have everything except the power switch and the inductor and capacitors. There are a growing number of switching controllers for currents on the order of 1A that also have the power switch included on-chip. You can buy all sorts of little modules that are designed as plug-in replacements for 3 terminal linear regulators and have everything except the output capacitor included.
The reference designs on the datasheets are excellent starting points. Often they're all you need. Be careful if you don't have the same parts that they use or recommend. Read their description before making substitutions. Most of the time there's nothing critical, but sometimes you have to understand what the part is being used for before you can make substitutions.

Maybe one of these?

Is this pretty standard stuff?
Is that the direction I should go here?·
Just follow the little schematics on the datasheets for them.
Thanks.
