I'm a little unsure when it comes to offsets etc so I'm seeking the advice of you guys To advise me if this wheel/tyre package fit straight onto my 997.1 turbo?

They should fit just fine.

Standard 997.1 Turbo rims were:

Front - 8.5jx19" ET55
Rear - 11.0jx19" ET51

The fronts you mention will sit just 4mm closer to the arch, less than the equivalent 5mm spacer commonly used and the rears give only 1mm difference over OEM.
Have a look at a tyre diameter calculator to see if the difference of OEM 19 and the 20 inch tyres quoted fall within the +/- 2.5% difference recommendation.
