See Ch 5 of the Customization manual again, and have a look at the file
theorems-ams.inc, where the original definitions of these styles are.
What we're adding to Local Layout is just modifying those definitions.
The syntax takes a bit of getting used to, but it's not too bad, really.

Sorry, I hadn't tested. You need also to add:
LabelString "Theorem \thesubsection."
and similarly for lemmas. Note that, if you want to use things other
than theorems and lemmas, you'll need to add similar modifications for
those styles.
You should also put, at the top of the Local Layout, "Format 60", that
being the 2.2.x format. This will avoid any possible problems from LyX
thinking you intend some other version.
