which brings up a Q of my own, if you use brass barbs, do you need to tap the plastic? or could you just screw em in the holes?

You'll find that they will go in alot easier and smoother (not to mention straighter!) if you tap first. I'm not sure if all barbs feature this, but the ones I use taper slightly out at the base so screwing them in will ensure a tight fit. Always use teflon tape!
