battery sensor schematic

Ok so im workin on my first electronic board. And this is my first post on these forums.

Im using a parallax propeller with an adc with a vref of 3.3v... I know just enough to be dangerous..

Heres my schematic...

Im sensing voltage with a simple divider. and using the allergro acs756 current sensor for current. Does this schematic look ok to you guys? am i missing anythign crucial? BTW i left the resistor for the 756 a ?? im not quite sure i even need one. but its there in case i do once the board is made.

I got teh 3.3v zeners there for proection and again not even totally sure i need them or not..

any thoughts would be appreciated. fyi your speaking to a total newb here.

thanks
