The tinkering doesn't have to be invasive or risky. I share your worry and am rather scared of breaking anything because of the amount of work I put into the configuration. My solution is to root very early on, just after testing everything and making sure I don't want to make sure of my 14 day return right, so if something goes wrong there I don't lose data. After that, I use root for all sorts of things, but after configuring everything I don't do invasive things like installing different ROMs or removing system apps or so.
