Your 3rd party (*see note) books can be stored on device under sdcard/kindle in the unencrypted mobi format, and opened via Kindle App. If you have books in other formats (pdf, epub), or in sizes larger than 50MB, you can convert them to mobi under 50MB using Calibre or similar program.
*Note: Third party books are books you did *not* purchase via Amazon. Amazon purchased books are encrypted mobi and just about worthless for reading on any other device or application (with few exceptions).
Kindle book downloads are encrypted mobi and not available to open outside the Kindle application. On a PC you can upload unencrypted mobi files to your amazon account and share to Kindle devices (or through Kindle application on Android devices). Also, the SendToKindle app is available from Amazon and installed on Windows at "C:\Program Files (x86)\Amazon\SendToKindle\SendToKindle.exe" (Windows 7 x64). Files above 50MB do not upload, so reduce the size using Calibre. Once these files are uploaded, you can web manage distributing
Not all Calibre book conversions give 100% complete formatting like image layout and bookmarks, so you may not get perfect results. Good luck
