I can answer the above questions.
Angora rabbits need a strong blower. A hair dryer won't do it. A blower is needed that is strong enough to split the fur to the skin, work apart the felting and clean the dander off the skin.
Metros are common and fairly inexpensive. I am actually a blower dealer. I use the K9 Fluffer by Electric Cleaner Company. They are expensive. I sell them for 360$ shipping included in the lower 48.

HOWEVER they are worth it if you are in for the long haul. I became a dealer because I was so happy with mine. Best money I ever spent.
I expect it to last 20 years or more.
I blow a rabbit in show coat every 1-3 days, depending on the rabbit.
Rabbits not in show coat, being grown for wool use or brood, I blow once a week, as I am not that concerned about the cheeks, shoulders or lower rear end.
I use a steel comb behind the ears only, and a cat slicker on the front of the back legs and in between the front legs and the ear tips and face furnishings. If I have a mat that got out of hand, I pull it apart with my fingers.
On the show table, I blow immediately before hitting the table, and use the slicker on the ear tips, the stomach and front of rear legs.
I wanted to add, after reading the above post, that yes, with french and maybe satin angora you can get by without a blower, but 'get by'. Really for the best health, a blower is a necessity. Not so much for the care of the hair but more for the health of the skin. Skin sheds in all creatures. In rabbits, it is prevented from falling away by dense wool. For those of you that don't use a blower or get by with a hair dryer, if you put a real blower on your animal, the result would be a snow storm of dander.
