Setting up HEQ5 & GOTO alignment

Yesterday, I received my first proper telescope. BT200 f/5 Newt with HEQ5 mount. I've assembled it all ... correctly, I hope! Got it balanced too. Tonight, weather permitting, I'll give her a go. I'm a little confused about the Synscan alignment. If I do a 2-star alignment, do I need to polar align the mount? Or can I just aim the North leg in the general direction of south? I can grab a compass and use my local magnetic deviation factor if true south is required.

Regarding magnetic deviation to find true south, I used the Australian Geomagnetic Reference Field Computation calculator and got D = 14.982 deg . Since that seems to be a positive number, I assume I use 195 deg. Correct? Or do I use 165 deg?
