Thanks so much for your questions. Right now, only videos and photos can be brought into the app through iTunes file transfers. You'll have to bring in PDFs using the "Download from web" feature and enter the URL of the PDF.
This also means that you'll need to put your PDF online where you can access. If you don't have web hosting, there is free web hosting at webs.com . Once you upload your PDF, you'd enter a URL that looks like…
For photos and videos, you can also download this way. However, you can also synch a folder with iTunes containing videos and photos. THen, you can load in the files.
The next version, v 1.2, is being worked on right now and is due to be released the first week of December. The next version will allow for PPTs and Keynote files to be brought directly into the app (no PDFs required) and you'll be able to transfer directly through iTunes.
