I'm starting Cyberpunk soon, what do I need to know?

Board 8

generally I open up with a overheat or short circuit on two people, throw a grenade while those are executing, and then clean up the rest

I'm supposed to be doing Dex's first mission - did the espionage part and met Judy, now I have to deal with the gang. But to get a hold on things I've just been looking for people with wanted levels and mercing them for practice and street cred. I was going to do an actual gig but it looked way above my paygrade right now.
If you wake up at a different time, in a different place, could you wake up as a different person?
