New to Marketo-- need a new Lead Process.

We are new to Marketo and use Dynamics--- we previously used a lead record to represent every conversion, so we are having to change this process to work with Marketo. (One Lead record or Contact Record that houses all of the conversion data)  Would any of you be willing to let a few us pick your brains on how Marketo works with your Dynamics as we outline our new process?
