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?

With DSLRs you can only get good and affordable lenses with limited focus ranges. The 550D I mentioned before does come with 18-55mm IS kitlens for the stated 650 euros. That gives you an ok-ish lens with wide angle to short portrait tele, a so called "standard zoom".
Similar kits can be found from Nikon, Pentax and Sony, obviously.
To get a set with simple but effective tele zoom, you can do two things. Either get a superzoom (which has limited image quality due to design constraints) like a Canon/Nikjon 18-200mm or Sigma/Tamron 18-250/270mm, or get a two lens kit with standard zoom and cheap tele, like the Canon 55-250mm IS and Nikon 55-300mm VR.
The tele lenses will give better results than the ultra zoom lenses.
A Canon EOS 550D with 18-55mm IS and 55-250mm IS costs a little less than €900. A higher quality standard zoom lens will take the costs over the €1000 mark.
A Nikon D3100 with a similar kit set will cost about the same.

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.

I still do not get where those figures come from, though (even if you got them from somewhere else)... The 450D uses 14 bits to store its information (luminance). The D90 stores 12 bits. This does not translate into 42 or 36 bits RGB values, though.. because of the non-linear mapping of the luminance values within RAW.
So, while one can say the 450D uses 14 bits and the D90 12 bits, both translate into 24 bits RGB (8-bit formats like JPEG) or 48 bits RGB (16 bit formats like 16-bit TIFF). There may be cameras where the 14 bits show an increase in actual information (like maybe the 1D mk III/IV), but the differences will be small. Between a D90 and 450D, I doubt any differences between the cameras are really impacted by the theoretical advantage of 14 bits over 12 bits.
