Welcome across to OZRS from another former Aussiefrogger and 205 GTi owner, and congrats on the purchase!
I jumped ship and bought my Titanium 182 Cup almost 10 years ago and am still enjoying every drive in it
As mentioned above, a quick pull (or push) on the driver's side window button should have it go up (or down) with one touch.
For the steering wheel - the Australian sun is not kind to them - I guess you could try cleaning and treating the leather (not sure if it really is leather...). Mine really needs to be re-covered.
I'm still on my original exhaust - haven't looked recent
