[Help! I have looked everywhere]

How to get rid of the blue dot when I touch the screen with my pencil. Its driving me nuts! Also is there a way to leave on the names of tools until one gets used to where they are, one last thing can I please make the background a darker grey? I cant find these questions anywhere and having been a graphic designer for over 20 years Im really looking forward to learning all of these programs! Its about time Adobe has a real challenger ❤️ Thanks all in advance for help!
