you can do all those things.
If they are of the Microphylla type you can leave them out as they are usually quite hardy. Milder here than where you are so a little protection is advisable. Dry compost or leaves will help.
i also dig them up....did this yesterday with S .Leucanthemum....more tender. I dug a large plant up and cut it in half, trimmed roots and potted up into 2 3 litre pots of mpc. These are in gh. In additional I cut a couple of smaller portions and potted these too.
I grow prob in excess of a dozen varieties varying from very tender to fairly hardy. Kept dry over winter they do well
should have added there are hardy types and you may well have these. You can divide these and replant but best left until spring. These do nof need any protection.
