what is the correct pressure for the S02s? in the manual it says 32psi yet in the FAQ it says 44psi.Are you better running the tyres slightly on the low side in a effort to warm them up quicker thus giving more grip?

Biker, there's tons of debate on the exact pressures to run. Before someone yells at you to run a search, most people are running a little more than the book's 32 PSI (always measured cold, not after a drive). The "right" number depends on what you're using the car for at that moment.

I do spirited street driving at 32 PSI all around. I Auto-X at around 41 PSI front, 37 PSI rear, but modified depending on track surface (grippy surface = higher PSI I can use). Some people reported better street tire wear life at 34-35 PSI so I'm going to try that next. Others reported dangerous handling characteristics at lower than 32 PSI.

Your final answer will factor in how you like the car to handle and how much oversteer you're comfortable with. I try not to get too sideways around town.
