I can't help with much of this but what I do know:
Cleanliness is next to godliness, traditionally and today Roma women devote a lot of their time to cleaning and childcare.
Contrary to belief they do not take their daughters out of school to mind their siblings whilst their mothers are lazy.
They do remove them to learn how to keep house, mind their kids, cook and clean and of course provide all the emotional support to the family.
The man is still the head of the household, but isn't awful and domestically abusive as reported. Of course it exists as it does in society as a whole, but no more so.
Different sinks I haven't seen, but I have seen my family members use different coloured bowls.
They have towels for show, not be used.
Toilet seats are always closed, I get told off for forgetting. This isn't for cleanliness though, it's to stop evil spirits entering the home.
Anything touched by an animal stays outside, so you'd wash animal bowls etc outside.
Everything is polished until it gleams and they get the best china off the dresser when you visit, and the spread of food would feed an army.
Perhaps because they were born into poverty. I couldn't cope with that much cleaning even if I was training a teen to do it.
I want more than that for my dd. My cousins children ( so once removed) are all very happy though, we see them as oppressed they see it as their life and generally speaking they are happy.
The modern day settled Roma seem to live a very similar lifestyle to the one their parents did. The same beliefs are apparent and passed down.
I visited an old Aunt, her home and garden were like a show house, amazing, lots of old antiques, brass, and china. There was no tatt and everything has a story attached.
Clothes are an interesting subject.
Traditionally when girls were between 11 and 14 they all left school, but unless academic the rest of society used to be like this too.
They were prepared to be good wife potential by about 16, working was unheard of unless it was dukkerin/hawkin.
Now, some, especially settled Roma stay on at school and have jobs, some even have careers. The traditionalists don't raise their dd for the latter.
So if they were to have an arranged marriage at 16, they would want their girls to be plain looking, a virgin was the only acceptable position to marry a gypsy. It was long maxi dresses similar to the 70's type.
Now it's anybodies guess, and those scantily dressed tweens with make up that you see on gypsy wedding do exist.
It's so sad that the girls are paraded this way, I'm not implying it's sexual at all, but a show to other families that their girls are being prepared for their future now.
My cousins girls all wear designer labels but nice dresses, this seems to be the thing these days.
Some travellers I saw recently in our town were buying half of Primark out, all the gaudy colours and prints that are usually left 
It was nice to see they could pick out clothes that were comfortable for them and obviously in keeping with their tradition.
I'm afraid my experience and knowledge about how they are supposed to act and what actually happens are two totally different things.
I do hope it isn't widespread but am witness to much hypocrisy in the never been kissed and still a virgin when they marry, even at 16.
I and many others I've come across are the products of this.
Sometimes the family would pass a baby off as one of their own, if there were too many already they were adopted.
Now, they terminate and it's kept between the female women in the family, the girls father or brothers aren't told.
