Buying back my old mkii

An opportunity has come up to buy my old mk 2 vrs back. It's a 2007 diesel I originally bought the car in 2009 and had it for 5 years amazing car loved it. Question is this what mods should I definitely do when I get it back. Wheel refurb is a definite and the body works needs some tlc and polish. Id like to lower it 20mm or that way just looking for advice on any mods that might be worth looking into. And what parts might be interchangeable that I can pick up second hand online etc. that's her back in the day.... Last photos are how she is now.
