Consultation on Rich Snippets - Google compliant / friendly

We have a WordPress Plugin that creates Amazon Product Posts. We need some guidance on what type of Rich Snippet format we should be using and the proper formatting of the Rich Snippet that Google and other search engines will display with out getting slapped or flagged for improper use or formatting issues that will lead to the Rich Snippet not being displayed on the search results. We will be adding Rich Snippets to the generated posts made by our plugin so we want to know the best Rich Snippet method and format to use. I would prefer to have an actual conversation either by phone or Skype to be educated on this subject. Good English speaking skills are a must for this conversation. I don't want there to be any confusion or misunderstanding when we are discussing this issue. I must leave the conversation knowing the answers to my questions with no doubt of how I need to proceed. Microdata seems to be the Google preferred method. And our product could potentially use one of these formats, Product, Author and or Review. Which version should we be using? Which Snippet display gives the best result, the most likely to be clicked on or what do searches expect to see in the search results? These, and others, will be some of the questions I would like to have answered. I would expect at least a 30 minute or longer conversation/consultation. Thank you.
