Hi Aceman,
Firstly, welcome to this great forum. There are heaps of knowledgeable folk here who are willing to assist us newbies.
I'm about where you are at with my new HEQ5 Pro mount.
I found the SkyWatcher manual a bit confusing as it also covers the EQ6 and much prefer the Orion EQ-G manual, same mount, different label.

And yes, you do need to have accurate polar alignment for tracking and there are several ways to achieve this. Using the polar scope in your mount, or if you have a lap-top, drift aligning or using a software program like SharpCap, the method I'm about to try when the clouds go away.
If you are going to use your Polar Scope the first thing needed is to align it. This is the most fiddly, frustrating, time consuming task I think I have ever done. The next trick is to find Octans in the reticle, which may be easier for you, being South of the Big Smoke with less light pollution.
I get the impression from various forums that I frequent that few people use the polar scope for alignment hence my decision to try SharpCap. I'll let you know how I go with it.
What camera are you intending to use. I had some frustrations in mounting my DSLR.
Keep asking questions and hopefully some much more knowledgeable members than me will chime in with solutions.
Good luck in your endeavours.
