We've designed OCS so that the technical expertise required to run it is minimal -- it should take a few minutes to set up and everything should be available via the UI from there on in. If you want to customize the look, you'll need to know CSS.
OCS 2.0 is a fresh release, so we don't have a lot of history to fall back on for concrete examples; however, OJS 2.x is an established product that uses much of the same code, so perhaps looking to it for answers would help. While some have heavily customized OJS to suit them, most journals have very limited technical resources and have often been publishing for years.
I'd suggest installing OCS 2.0 and exploring it, if you haven't done so already; that might answer your question.
