the same shutter speed.
Also, any info on links, books or tutorials would be appreciated.

I think your "local guy" was right... You will rarely need to set the |
shutter speed manually.
However, the light sensitivity of todays cameras is such that in
daylight you *can* if needed use very short shutter times e.g. 1/5000.
If for example you want to capture and analyze some sports activity such
as a golf swing, you would probably want to use a very short shutter time.
To actually "freeze" a driver head, 1/4000 is necessary.
When such a clip is played at normal speed, a viewer can sometimes feel
that is has a "stroboscopic" feeling about it.
It seems that the human eye likes the "smear" that a longer shutter time
gives.
When changing channel on my settop TV box, the picture stays frozen for
a few seconds or so before the new channels starts. Then, it is easy to
see that they use a fairly long shutter time because of the "smear".
However, slow-motion replays of ice-hockey or other sports are often
recorded with shorter shutter times giving a sharp still picture.
To sum it up, I *think* it is like this: If you want sharp frozen
frames, set a short shutter time manually. If not, leave it on auto.
Some cheaper cameras don't actually let you set the shutter time, but
instead they offer a "sports" setting, that has priority on shutter time.
