No need to grease anything on the top. You may want to check about some of the convertible top conditioners, Ragtop may be one I recall, also there are others on the market. Overall these tops hold up pretty well for 10+ years. I have a 2003 I purchased new and it has spent most of its life outside and still has the original top. That being said the rear window started to come unglued last week, much later than many others, but this is not VW specific problems, it just happens over time on most convertible tops.
Suggest you purchase some sort of VW specific scan tool and/or a scan tool that will also read real time data.
You likely will need a thermostat replaced soon. They go soft and the engines run cold and this can be a long term problem. The engine should run very close to 205F.
Suggest the VAG405, but it does not read real time data, so you will also need an additional tool to read real time data. If you have an Android phone, for $20, you can also have a tool that reads real time data.

Also suggest you plan on a water pump, timing belt and belt tensioner replacement by 75k miles since you want your daughter to have a reliable car and to not have a catastrophic engine failure. Also if the car is an automatic transmission, be on the lookout for harsh 4-3 or 3-2 downshifting. This is a symptom of a transmission valve body going bad. ALL the VW automatics of this vintage are having valve body problems, usually by 70-80k miles. Fix the valve body as soon as you start to have harsh shifting. Changing the trans fluid will not really solve this problem, but it would help delay the problem.
Hopefully you will not have any door latch problems and you have at least 1 if not both keyfobs as well.
Good luck, sounds like a nice car, just keep it well maintained.
