I await other's replies anxiously. I too am in the same place, though I consider myself on the fence, approaching intermediacy.
I find - although it contradicts your theory of drowning in knowledge - looking at the main line or two behind openings you see yourself playing a lot. Under the learn tab on this website there's the "Book Openings" section; not sure if that's a members only thing but I find it helpful.

Is there a simple book or software program that would help me digest about 4 openings?
And if I play black, do I need to study an opening defence?
