Answer 1

Your scenario is NOT supported by Microsoft according to the KB article Considerations for server-side Automation of Office which states that

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

The article then goes over alternatives to server-side automation one of which is Open XML. You might want to check this article out if you haven't already done so.
