Obviously, I've consulted the internet on what should be done. It hasn't been extremely helpful but I came across a few interesting articles.
Pocket Cultures has a short article entitled Kiss, Hug or Shake Hands? It summarizes the types of greetings that are commonplace in Argentina, Brazil, Great Britain, Romania, Singapore and India. Its not just about the hugs and kisses, there is also a guide on what the usual response should be to the simple question of 'How are you?'
This article from the BBC is lengthy but offers a quick guide on the number of kisses:
Three: Brittany, Netherlands, Belgium (if other person 10 years older), Egypt, Russia, Switzerland
Two: Spain, Austria, Hungary, Greece, some parts of France
Close friends and family only: Germany, Italy, Middle East (except between male friends)
Don't try it: Japan (bow)
And finally, there was this funny article from The Australian. Its written from a man's perspective on the confusing air kiss. This isn't the only article that mentions it, but it looks like social kissing in Australia is a fairly recent, 'fashionable', behavior.
Anyway, there are three days left to Christmas so I'll be putting my hugs into practice. I don't think I'm advancing to the social kissing level yet but who knows, maybe next year.
