Hello CF Brain,
We are happy you like our product. Thanks!
If you want separate pie charts with separate legends I will suggest you go with having two charts on your page. Each will have its own legend. If you want to experiment with custom layouts you can take a look at our first look example
2nd question - It will be possible beginning Q1 2010 to easily query and change each individual color of the chart palette. Currently it is taken from a built-in palette different for each theme.
