Arrow root is akin to cornstarch in that it is used as a thickener and
binder in many baked goods (this is popular with natural food fans and
vegetarians) in fact i think some vegeos make a geletain like dessert with
arrowroot, but dont quote me on that.
As for removing it from the paleo bread recipie, you might need to add some
other binder? Eggs? Perhaps.
I'm also not sure about this but arrowroot is a tuber, so  yes starchy, but
less so than some things like corn or other root veggies. I don't really
know, anyone else know where to look those things up?
I've made delicious nut bars using only honey and dried fruit as a binder.
THey are harder, but still quite delicous.
I used acorns walnuts, dried raisins/apricots, maple syrup or honey, butter
or oil and maybe some ground oats  and it is quite delicious. You could of
course eliminate the oats. I just mixed it all up in the food processor,
presed into a pan and baked until hardened...
sorry idont ahve a more set recipie, i make things up as i go.
GOod luck
