InfoPath Dev

I have an InfoPath 2010 Client form with Full Trust and I need to submit the data to a Sharepoint list. (See Attachment) On the form I load up events from a Sharepoint list and I need to collect whether the user will Participate or Assist. I can't figure out the best way to get this to a Sharepoint list. What would a CAML file look like? I've only seen examples of a CAML from Main fields.

Notes on this form: Event, When and Location are Read Only. Participate and Assist are editable checkboxes. I would also be happy to get this form, as completed, into a Sharpoint library as a PDF. I tried entering the following VB code:

Public Sub CTRL50_5_Clicked_1(ByVal sender As Object, ByVal e As ClickedEventArgs)
Dim fileName As String
Dim nameNode As XPathNavigator
'Set the values. Replace "/my:myFields/my:textField" with the xpath to the field that has the value you want as the file name
nameNode = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:Name", NamespaceManager)
fileName = nameNode.Value + ".pdf"

'Do the work -- notice we use the variable fileName as part of the path for the file
Me.CurrentView.Export("http://mmsp/it/FacAdmSvcs/drs/cc1/" + fileName, ExportFormat.Pdf)
End Sub

And, the form is submitted to my library. The problem is that the Secondary data coming in isn't saved.
