The calculation time is per move, so it depends on the level of the game,
computer speed and the total time you want it to afford. Note that it will not
only check the moves played, but also create variations and sub-variations
move-by-move (not just insert pvs), sometimes. For a first test to see how it
works, you can try 3 seconds and increase later when you are more familiar with
it.

The threshold is the key setting of this function. It means the +/- difference
between the evaluations of the move played and the engine's pm. I recommend to
increase it to 0.75 or 0.80. With very small values, it will create a lot of
"debatable matter-of-taste things." With higher values, it will focus more on
moves which it thinks to be blunderrandom. :)

I'm not 100% sure, but I think all types of engine will work with that function
if they work in Fritz at all, generally. I would recommend Shredder 9 or Hiarcs,
as they have very good hash learning (games will be analyzed backwards), afaik
Junior 9 too, or of course Rybka because it "simply" is the strongest engine,
currently.

>Do the written text comments help in any way?

Yes, some of them but not all. Some will really make sense and point you to
interesting key positions, some others will seem somewhat dull. If you want to
create analysis for a club magazine, chess homepage or something like that, a
knowledgeable human's review and editing will be required. But it is a good
basis for the interactive analysis to follow.
