You're welcome - and yes we are always interested to get a hand on files which can not be rendered correctly. Please try to open them using Adobe Reader/Acrobat too just to get an idea how they are processed there. Sometimes we get PDFs that are so corrupted that there is not a lot we can do about it.
For all usage questions the users mailing list is fine. If you are sure or think you found a bug please open an issue at https://issues.apache.org/jira/browse/PDFBOX with a test case to reproduce the issue and the PDF in question attached. If you have an idea how to overcome the issue you can also attach a patch for us to review. Good luck with your project and feel free to ask additional questions as they arise.
