check
I am doing background/rebuild but I type slow and will post in RG tonight.
I will not be taking armor (i will take a light shield) but will be in total defense alot lol.
So my AC Should Be 16 = 10 (base) + 1 (cloth) + 2 (light shield) + 1 (amulet of protection) + 2 (dex)
And 18 with total def and the defensive healing word feat I am taking
Is all this ok??

You've got your AC off just a bit. The "base" is 10 + 1/2 level, so 11. Cloth doesn't actually provide an armor bonus at all, but you do have a +1 enhancement bonus inherent to you, so 12. The light shield only gives a +1 bonus to AC and Reflex, so 13. The inherent bonus to defenses (neck slot item, or "amulet of protection +1) doesn't affect AC, only Fort, Ref and Will, so still 13. You would get to add your Dex mod at +2, so 15. This is a low AC, but like you said there are other targets and a couple of defenders to try and keep melee enemies off of you. Still, artillery could be a major issue. Total defense would add 2 to your defenses, but it takes a standard action to activate. Even without damaging powers, you can usually find something better to do with your standard. Also, Defensive Healing Word only gives the bonus to the target of your Healing Word and only against one attack. If you're using your Healing Word on yourself enough for the feat to significantly improve your defenses, you're pulling that healing away from the group as a whole (not that this can't be done, you guys do have two leaders).
If you're dead set against chain, I can understand that. I would still recommend it, or at least leather or hide to bring you a little higher. Since you have a shield already, you may want to bump it up to a heavy shield to give you another small boost.
Comparison:
If you get leather and up the shield, it will raise your AC to 18.
If you get a heavy shield and go with Hide, it goes to 19.
If you get a heavy shield and chain, you'll be up to 20.
Compare this to Sathi, the other leader, who also has an 18 AC (without a shield). As you level, this disparity is going to get bigger. Your Dex won't be improving much (likely only +2 all the way through epic) and light armor almost demands that your Dex or Int be improving faster (this is why light masterwork armors [which you all will get starting at level 13] only go up by +1 armor bonus at a time and heavy masterwork armors go up by +3 armor bonus at a time.
So at level 13:
If you stick with what you have you'll have an 18 AC (+2 from enhancements at 8 and 13, +1 from masterwork armor)
If you move up to leather and heavy shield you'll have a 21 AC
If you go all the way to chain you'll have a 25 AC.
Sathi should have a 23 AC at level 13 without picking up a shield.
So with that in mind, how do you want to do it?
