Editing/Managing a TimeSheet via a Web Part

I have a question about creating a Web Part that allows for Resources to enter their hours into TimeSheets.

I want to make sure I don't alter the Project Server Timesheet publishing sequence.

My question is, to use the web SVC TimeSheet to call SubmitTimesheetLines() which Database should my web part update to?  I

I went to My Tasks and updated some hours but I do not see them in [ProjectServer_Reporting].[dbo].[MSP_TimesheetActual]

Are they in [ProjectServer_Reporting].[dbo].[MSP_Task]?

And are there any other functions I should call before I call SubmitTimesheetLines() like PrepareTimesheetLine()?
