Disclaimer: I'm going to assume that the stats are still flexible. If not, disregard the text below
First, you should consider a lower INT and CHA: If you are considering being both a tank and a healer, then you cannot afford to also be face and skillmonkey.
Second, you are using your precious points from leveling up (and even a manual!) to increase your one of your lowest scores from 13 to 16: You'd be much better served by starting with Dex 15, using a level up to get to 16, and use those extra 3 points to start with a slightly higher STR (you can even get to 15 by just lowering 1 point in int or cha).
Still, if I were you, I would try to increase your STR a little more: part of tanking is dealing enough damage for your enemies not to ignore you.
My suggestion of stats would be
Str 20 (16 + 1 manual + 3 level up)
Con 16 (14 + 2 racial)
Wis 16 (14 + 2 racial)
Cha 8 (10 - 2 racial)
