I don't know anything about the Agfa numbering, but as to this question, the TIFF file is lossless, while the JPEG is lossy. That means that if you edit and resave JPEGs, there is a loss of information with each save. I've seen this in as few as five resaves. The TIFF provides a lossless image, which you can work on in your processing software, then export as a JPEG, when no further changes need to be made. That's a very similar workflow to the way I process RAW files. If you don't plan on doing much work with the files, it's perfectly acceptable to save them as JPEGs, which take up a lot less disk space, but since I have a large amount of space and like to fiddle with my images, I'll continue to save the original files as originals. Others may have different thoughts and processes.

Or you can copy your JPEGs and work on the copy, leaving the originals untouched (opening and closing JBEGs doesn't cause any loss of information).
