She IS angelic.
I'd bathe your kitten every week. Especially since she's white. My last Persians lived until 19 & 20, had a bath every week and never got dried out or knotted. Being bathed often made it easy to keep them in coat their entire lives. Bathing is the key to easy grooming, imo.
If bathed weekly daily combing should only take 5 minutes. Very little hair should come out each time, except during shedding season. If a handful of hair is coming out - you're probably using the wrong tool.
When you get the metal combs - get two sizes.
These aren't the ones I use but are an example:

Also, I recommend a certain type of pin brush: available from petedge.com - it's worth it because it's hard to find pin brushes that don't have "balls" at the top of the spikes. If you get a pin brush, make sure you get a "large".

All I ever use are two metal combs, and eye "makeup brush" (without anything on it) and the pin brush.
I use water in a mist bottle to cut down on static when combing. Not too much water, just an occasional spritz.
The eye brush is to fluff up the little short hairs on her face, forehead & ears.
The pin brush is mostly for fluffing and the fun of it.
Since I spend effort keeping the cat immaculate, I believe I deserve the fun that the brush provides (even though it's not really necessary).
