Hi Patrick,
Have you looked into the
web page activity report to report on number of visitors to your web page? This sounds exactly like what you were looking for and includes pages with the munchkin tracing code on the web page.
For the others, you may want to consider:
# of Emails sent, opened, clicked = Email Performance Report
# of Visitors to Marketo LP = Landing Page Performance Report
# New Leads, Unsubscribes = Lead Performance Report (group by either created date or unsubscribe)
# Form Fills - you can do this using a Landing Page Performance report to see how well the page is converting, but if they are on an external web page you may need to use a smart list to do this.
