Biking to work

Sorry in advanced for poorly drawn image

I’m thinking about biking to work and curious on the right way on foing it. It’s about 3 miles from my house to where I work. Yellow dots are stop signs and the red and blue lines are main roads where I live and there’s no bike lanes and all roads are two lane but there’s some space on the side but not a lot. I’ll start by approaching the red line and turn right and then turn left onto blue and then an immediate left on white towards the ball fields. The speed limit on red and blue are 35 mph. From where I turn onto red to turn onto blue is about 500meters. From the school to the ball fields it’s downhill

And for the way back home I’ll take the two rights then a left.

Should I ride in the road or should I try to keep right and if I stay right how do I safely turn.

Also how do I safely travel at night I have several flashlights and headlamps and some red plastic I can put over some flashlights to make tail lights I also have two red reflectors I can put on my bike

Sorry if my post is a bit confusing
