A3 -55 2.0 fsi new buyer advice please

I am a new owner of a 55 Reg A3 2.0 FSI sportback SE...

It was a Impulse buy as I wanted to always own a A3. The car is @ 100k.I intend to pop over to Audi for service history details and full service..( as the seller has lost SH);It passed MOT last wek without any advisories...I had a short drive and everything is prima facie ok..

I know that all VW stable vehicles need a cam belt change @ 80-120 k/4-5 years so what should I look for in terms of sorting it out??

Once I do that then probably I would look @enhancements ....

thanks ..

Ok still looking forward to some replies about what should I look to get sorted with getting it long life serviced and cam belt changed..

Also noticed that I have 20 inch radials...So probably fuel consumption will be on higher side but better road grip...Any recommendations on replacement...
