You like those run-on sentences, don't you? Please make an effort to punctuate correctly.
About renew it's fondamentally a personal choice i think, rely on your own playstyle. I personally manage to have it always on tank(s), but for spikes on raid i feel more confortable just using direct heals, and thus i won't go for glyph and will take 1/3 for both renew talents... i find hotting up pretty useless when the damage burst is huge, because or it won't be enought to keep the target alive or it will just overheal, after your raidmates topped him off with a direct heal. Also, glyphing means that you would have to "waste" a GCD more often to keep up a fairly weak spell.
About inner focus, i personally picked it up, but didn't really needed it most likely... will discover it in more manastressing encounters i guess
