there is no such a thing as recommended shutter speed. it will be different in every situation. it depends on your ISO and aperture settings, which are obviously different for every lens.
The camera has an Electonic meter / exposure compenation display (fig. 3 on the left image). Use that as a reference.
It will change when you play with aperture, shutter speed and ISO. Keeping that display at 0 is usually a safe bet to begin with,
and then adjust the settings according to your liking.
and i always shoot in manual. auto would probably give you decent results, but i wouldn't bet on it.
