Hi Mike - Welcome to Pherotalk.
I’m in Scotland and I’ll say now that AD’s delivery to the UK is expensive but it is also far better than any other phero seller I’ve used - In Europe or the US. All the others can take weeks, whilst AD is only a few days. Customer service is first class too.
Yes, there are pheros here that will help you and a lot of other advice on changing your behaviours/becoming more attractive. Do plenty of reading. 
No one phero is best for ONS - All sorts of factors can apply here and someone can respond strongly to you wearing a social, status or sexual phero - for various reasons, the distinctions can be blurred and its all up to your behaviour and their response to it and the pheros that counts. Trying, finding what works with your own body chemistry and personality and at what effective dose is the only way with any certainty.
Particularly this thread, which covers all the basics on choosing and using pheros effectively:
Smoking and pheros - that gets asked on an almost weekly basis! There are many threads here with more detailed explanations but the answer is a qualified no, as smell/scent is the carrier for pheros, not the means of response. However, smoking can inflame the nasal passages and surfaces that absorb the pheros, so there is a possibility of some degradation there - However IME it is not a lot.
