Beginner questions fs2020

Hello everyone Just passed first solo flight and trying myself first solo flight with other Cessna c4j here my questions

1. while I do flight plan, the sattelite images on world map so blurry, I downloaded some area but still didn't fix the blurry
2. after landing, cant see the parking or taxi ways (name signs) on Minimap
3. after I reach the desired altitude, I cant switch the auto pilot, am I doing something wrong?

What's "must have " add-ons?

Thanks
