to my .emacs, there's only 'RET' in the line at the bottom instead of
a simple return in the buffer currently edited.

Why does this affect the return-key and how do I get my custom
shortcuts without harming my enter-key?

That's because in the ASCII character set \C-m (a.k.a. "control M") is the code for "carriage return." Depending on your platform, you _may_ be able to get your Emacs session to distinguish between typing the RETURN key and typing the M key while holding down the control key. But don't count on it. You can save yourself a lot of time and grief by just getting used to the idea that \C-m and RET are the same thing, and never trying to use \C-m as anything else. (By the way, \C-i is the ASCII code for TAB, so you may as well resign yourself to that as well.)
