Answer 1

We use Apache POI to read Microsoft Office files. There are many libraries for PDF in Java. iText is something I have used. Once you pick the tools, do a selective search on Stack Overflow . There are plenty of discussions around these tools.

Answer 2

Depending on the types of updates you are doing, modifying PDF is going to be a problem - it's not intended for editing. You might have to find some way of converting the PDF to something first, then edit. Depending on the types of changes you want to make and the documents you are working from even editing DOC and Writer files is going to be tricky. They are all different formats.
As Jayan mentioned, iText and POI may help you a little. OpenOffice Writer documents can be edited by unzipping then modifying the XML or using the UNO API. Word documents can be editied by using MS Office automation (bad idea), converting to OpenOffice first then editing, or if DOCX, unzipping and processing the XML.

Good luck.
