You should be ok with that. 14-16 is generally what I argue as being ideal for starting Str.
8-12 is too low and you lose out on Power Attack.
Over 16 is too high and takes up way too many build points.
As for Wis, I think the general goal is the 28-32 marker for endgame for a reasonably good DC on your finishers, QP, Stunning Fist, etc., but you can boost yours further with 2 level up points if you were so inclined, as well as +2 exceptional wisdom from an endgame item. So you should be ok.
As for AC, I think your average Monk is going to be at 50+ AC endgame no matter what they do, unless you ignore Dex and Wis completely.
For example = 10 base + 20 (from 30 dex and wis, or an average of about the same total) +5 (centered) +8 (bracers) +5 (protection/deflection item) = 48 AC.
Throw in some other goodies such as a chattering ring or seal of the earth (+3 AC), shroud insight gear (+4 AC), icy raiments (a further +4 dodge), and you're now at 59 AC. 60 if halfling.
Throw in clickies (shield = +4 AC), barkskin potions (+3), haste potions (+1), defensive stance (+2, +5 if combat expertise), etc. and you're now mostly untouchable at 70+.
Raid buffs add a further +2 (full barkskin) +5 (paladin aura) +4 (bard AC song) putting you at 80+ generally.
And the worst part is, I'm sure I'm missing some AC there somewhere. At work and can't be arsed to double check, but yeah, it's probably going to be even higher.
*edit* - found 2 more AC. 1 from Dodge feat, and 1 from alchemical formula (crafting). I'm sure there's still more
