You advice is suspect and your grammar is atrocious.
"to ArP or not to ArP" : remember that battle stance gives like 6% on top of w/e ur at, and if u get the T9 bonus, its 16% on top of w/e ur at, so keep that in mind when geming. im currently sitting at 50%, including the battle stance T9 bonus so i would usually gem for Str instead.
for the rotation quote, i have yet to expiriment with that, for fury its better to stick with rotation, and frankly i think with arms it would probably be the same, hitting execute when ur at 50 rage or more, or somewhere near there. test it out, see what u think.
