Hi Craig,
Sorry, I don't check on this forums over the weekend.
For #1. I notice that you have two Save to PDF script steps. You don't need the first one and just need the second. Make sure that you've selected "without dialog." That would take care of the saving part.
For #2. In the email setup dialog, at the very bottom notice the Attach File checkbox. Select the box. And then in Specify enter the $path variable.
This should take care of it for you. Let me know if you're still having trouble.
David.
