I placed one of the brackets on the wall and it rocked from side to side
as
the pebble dash is uneven. I am wondering if this will resolve itself once
they are securely attached. The other question is what method of
attachment
should I use?

Level the surface behind the brackets with external filler, then drill and
plug as suggested by others.

If they are rocking now, I'd assume they will eventually fall out.
