Answer 1

I'm not sure how to do this through XAML , but I instantiated my ReportViewer inside of my ViewModel .

WindowsFormsHost wfh = new WindowsFormsHost();
Reporting.WinForms.ReportViewer rv = new Microsoft.Reporting.WinForms.ReportViewer();
wfh.Child = rv;

I then set my parameters, ProcessingMode , path, etc... for the ReportViewer in the ViewModel including setting

rv.BackColor = System.Drawing.ColorTanslator.FromHtml("#151515")

This successfully changed the background color in the ReportViewer You may need to call RefreshReport() before you see any effect.
