Naor,
This is a great workshop to run. I would use Marketo's Content Marketing and Definitive Guide to Lead Nurturing as bases for your framework.
You will also need to manage your team well and keep them focused on:
- What content exists?
- What content do we need?
- what is the goal of content/specific pieces?
- how does this help the buyer learn about their need, our solution, and choose us?
