Probably much better chance of getting them healthy if she digs whole plants.

In another thread on huckleberries somebody suggested using a spade to sever the roots around the plant you want to take. You con do that a month or two ahead of time to allow the plant to adjust to the lower root mass. You could then dig them up with the remaining roots intact and minimize transplant shock.

Best to move them while they are dormant.

If you take cuttings I'd expect it best to take them while dormant. There have been other posts on gardenweb on how to get cuttings to grow.

It can be as simple as dipping them in rooting hormone and sticking them in the ground outside in growing medium suitable to blueberries.

It may help to allow for some humidity and perhaps partial shade the first season while they are getting established.

I've managed to somewhat successfully get some plants goin indoors under flourescent lights using dormant cuttings from the germplasm repository in Corvallis Oregon.

Andrea:

Save some excitement for around January or February, when the plants are fully dormant. If you try to move blueberries now, whether they be whole plants or cuttings, they will die.

It is possible to start blueberry cuttings taken while dormant and stored in refrigeration, by dipping them in rooting hormone and planting them out in acidic soil in early spring.

But if you are a beginner, and can get whole plants, by all means take them. You will reduce the time to fruiting by several years.
