They’ll teach you this stuff in the MSF course.
I’m assuming that when you ask “how do people stop at red lights” you mean because starting again is the hard part. The stopping part is easy.
As for the daily check, some of it’s important. They’ll go through a basic checklist at MSF for what you should do before riding. I’m pretty lazy about it though. I check the important things like the tires and sometimes the oil, but a lot of it I can determine if it’s good or not on my way out of the place where I park.
