Some types/subjects would benefit with wide angle (landscape/city space/architecture), some with tele (animals, football matches).
The by you stated price of the quite low fixed €650 makes me have the idea that the budget for lenses is also limited? This then means that for the moment you can not yet buy a diverse set of lenses for all purposes?
I will leave the lens advice for now, even though it is sort of linked to the choice of the brand of body.

Let the limit be about 900 Euros, 1000 euros as a last resort, both for body and a lens with a wide angle. I'll try to find money for other lenses in future. Are there some Kits with an adequate lens in order not to buy an additional one?

I am not sure where you get those bit depths from. DSLRs have a bit depth of 12 bit or 14 bit. That is per pixel, each pixel only containing one colour.channel (R, G or <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/cool.gif' class='bbc_emoticon' alt='B)' />.. The values are not spread in a linear fashion, they will need to be spread out in a different way during conversion of RAW to fit in JPEG or other normal image formats (like the different TIFF formats and such).
JPEG has 8 bits per channel, so 3 x 8 = 24 bits per pixel. TIFFs can both have 8 bits and 16 bits per channel (16 x 3 = 48 bits).
8 bit per channel formats might also have an alpha or transparency channel, making it 32 bits per pixel, and 16 bit per channel formats which include an alpha channel will then have 64 bits per pixel.

The depth 36 and 48 bit per pixel wasn't invented by myself. For instance, Canon EOS 450D has 42 bit and Nikon D90 has 36. Due to your discussion the situation become clear.
