How do I implement both Schema and Rich Snippets and how beneficial are they to SEO and the Serps?

Read the schema (nutrition for example): http://schema.org/NutritionInformation

Actual example of nutrtion data, look at source: http://www.xanderfit.co.uk/food-database/view-food.php?id=5386

Look for itemprop, itemscope and itemtype, that's my site so if you have a specific question, then ask...

As for SEO and SERP, it allows the search engines (and other things) to understand your page better, which could convert to being a better served result than a competitor.

This is an extremely valuable link. Thanks Smeagel13.
