Nifty right? Just leave that 2 in the denominator, and then for sine you go up from 0 to 4. Then for cosine, you just go down from 4 to 0.
For tan, I only used what made sense to me. I just memorised tan(π/4) = 1 and then was like
Ok, √3 is always involved when I'm dealing with tan.
The smaller tan(π/6) goes with the smaller 1/√3
The larger tan(π/3) goes with the larger √3

How well do I need to know preliminary trig for HSC, any specific topics in particular?

You need to know all of it, all prelim content is assessable at the HSC level! Particularly, you should be good at using the sine/cosine rule and solving trig equations, they are the most common, but you need to be familiar with everything! ;D
