Welcome to the Q&A Forum

Hey Steve!  If you have specific questions about reported site crawl issues, you can shoot us an email to help@moz.com.  However if you are looking more for someone to show you how to fix them in Magento, you would need to reach out to Magento support or an SEO consultant to work through the issues as we unfortunately don't offer consulting.  Feel free to reach out to us at that email if you need assistance with the Moz toolsets. thanks
