I recommend not doing a secondary. if you must, just be careful racking from the primary and don't get too greedy in trying to pull every drop above the trub. screens or other filters are unnecessary IMO.
as for bottling, if you use a bottling wand and avoid splashing, you should be fine. I find if you plan, track your steps, and take good notes, you'll identify your mistakes much better than I or anyone else will.
most importantly, no need to overthink it. in the wise words of charlie - RDWHAHB
