On the Praktisix II (two, not eleven), you may have more luck to find online resources when you search for Pentacon Six - they are basically the same (Edit - my memory fooled me after ~30 years since I used both, but still very similar:

If you're a newbe and think of black and white film, you may want to consider Ilford XP2 Super - it uses a color development process, which is much more standardized than black and white development processes, and thus delivers rather consistent results even from different decent quality labs. Otherwise, for actual black & white film, you need to either find a reliable lab with consistent (published) development procedures or learn to develop film yourself.
Outdoors, ISO100 film will usually be OK during the day, ISO400 is only needed when light fades or under thick clouds. Indoors, it's often not enough, but there are a lot of parameters in that decision ...
