rs350

So I bought a used 350z roadster in average condition roadster,waiting to pickup .. can I get some feedback on options around addressing a few issues with the condition see images.
1. Tear in roadster innner lining where it wraps around the bar .. I think sowing a rectangular patch to strengthen it in should repair this. But any background on this specific type of issue
2. Weather worn window strips - from been parked outside .. replacment rubber weather shielding available? Or as a hack black liquid silicone adhevise tube could be used to replace this and fill in the gaps?

thanks
