You need to do more work if you want to have id' only for the top
few levels, then you first need to find out what the level is.
You can look at the dynamically scoped variable `head' which will
contain the stars to be inserted (and, maybe, also a space,
careful there)

On the other hand, I don't see why it it would be a problem
to have ids in headlines below the limit.  But I do not yet know
how well my ID mechanism will scale.  Should be pretty good, actually.

No easily.  The fastest way to get one added by hand is to store
a link to the heading with `C-c l'.  If `org-link-to-org-use-id' is t
or 'create-if-interactive', an id will be added.

Since no special function is called when you type a headline,
it would have to be advice to org-self-insert-command.
Very likely that would significantly slow down typing, I strongly
advice against doing that.

(org-map-entries '(org-id-get-create) "LEVEL<5" 'agenda)

Make sure the scope (here `agenda') is so that you will reach the files
you want.

M-x org-id-update-id-locations RET

See the docstring to make sure it will reach the right files

They already are in the HTML, I am surprised you never noticed.
