Is there a file in Logic that contains all userdefined keycommands, so I could simply make a backup and overwrite after a new install, instead of reconfiguring my keycommand-set?

Yes, there is. On PC's it's called Logicxx.prf and is located in C:\Windows. On Macs it's "System Folder : Preferences : Logic x Preferences". If you want to import key commands from a preferences file, open the Key Commands window and from the Options menu pick "Import Key Commands".
