I have about 25 angoras. I have been keeping them for a year now. No harder to keep than any other goat but they do need clipping every 6 months. In summer you need to keep an eye out for fly strike. We have been using crovect for treatment for lice and for prevention of fly strike. Also you need to get hands on regularly to monitor bodily condition as it is hard to judge under all the hair. We have just started clipping ourselves. We have used a shearer in the past but this is uneconomic to continue. You could probably buy some hand clippers as the shears are expensive. They are prone to stress oedema (google it) after periods of stress; weaning, transport, clipping etc - some lines more so than others.
Regarding pygoras I would say this is a bit like cockerpoos and labradoodles - someone has just crossed an angora with a pygmy and wants to add value to it - in reality its coat will be of very little value and you will still need to shear the goat so my answer would be get some wether angoras if just for pets as their coat retains a relative value and eat pygoras!
Hope this helps - there are some angora breeders in Wales if there aren't many breeders in Ireland - search British Angora Goat Society. I have some for sale but fear I am too far away in Yorkshire!
