If overfilled, we've only seen it come from the breather. The simplest way to describe the correct oil level in the glass, is if you see something, anywhere in the glass, your ok. If yours is halfway with none blowing out, great. If yours wants to be at the bottom edge, great too. Lots of the 1100-1150 bmws are the same way. The BMW book says half way, but lots seek their own level a bit above or below the line. obsessing over an ounce or two of oil is counterproductive.
For safety, I don't like te idea of running an overfilled bike and letting the oil blow out. Best I think, to drain a bit out. It's a pain, but safer and cleaner.
Re: pre-emptive loctite? Tank bolts, fender stays, exhaust flange nuts is what I suggest at delivery. During break in, put a wrench here and there to check things over for bolts unique to your bike. my opinion.
