I will say Bobbi Brown does a really good range shades wise of foundations. I am Scots/Irish/English with a bit of Viking in there. LOL I am fair but have warm undertones, not the true pink undertones of the Irish.
Have to say I find Lancome does not have a good shade range.
Prescriptives was the best for texture and shade choices, really missed.
I would go to the Bobbi Brown counter and get them to colour match you and get a sample to try over a few days. Always better than paying for a full size and not being happy.
Cleansers, well don't over strip your skin as it will compensate and make it more oily. A muslin cloth is great for removing cleanser and gives a gentle exfoliate as well. Clarins are really good at giving samples out to try. Not sure how easy it is to buy Liz Earle in the US? She does a cleanser with a muslin cloth and thousands sweat by it, simple and does not strip the skin.
