We created a project with all the properties set as you described and entered the text you provided. Upon export everything seems to work as expected. All the text is with Trebuchet MS font when opened in MS Word. We would very much appreciate if you open a support ticket and send us a sample project with some steps on how to input some text that eventually will be exported wrong.
On your second issue - you can use SectionDefaultPageMargin property to decrease the distance between the text and the header. For example if you want to decrease only the distance from the top, you can do something like:
Padding padding =
Padding(padding.Left, 0, padding.Right, padding.Bottom);
Unfortunately, we have a bug in our export as you mentioned, which we will fix in the Q2 2012 release which is about to come up in a few weeks. We updated your Telerik points in appreciation for the bug report.
