I have two Templars: one magicka Healer and one stamina DPS. Yes, from what you described, it does sound like you're a bit all over the place with your build. Here's a few tips:

-- Don't spend your attribute points evenly! You can't do it all, and you're hurting yourself in the long run. You said you'd like to DPS, but do you want to be a magicka DPS or a stamina DPS? It's virtually impossible to be both. I personally prefer stamina for a Templar DPS, and of course magicka for a Healer. Whatever you decide, you can do one of two things: 1.) Drop ALL of your attribute points into ONE stat (Stamina or Magicka) or 2.) Put at least 10-15 points in Health for survivability, then put the rest into either Stamina OR Magicka.

-- 1h/Shield = Tank. Forget the Sword+Board if you want to DPS; it just doesn't put out great numbers. 2h and DW are excellent choices for melee. Bow is a good secondary (or primary, if you want to be a ranged character) for a Stamina build. If you do decide to go the Magicka route, Destro/Resto is probably your best bet.
