You've given more than enough now.
Sound like you are new to smartphones, so let's work on your first need, getting from monterey to valleyo.
As far as follow up and continuing learning, remember that android will more than likely do what you want, you just need to figure out how to do it. We have 1 million+ members here that like helping each other, so you just need to ask what you want to accomplish and someone will try to help.
So, back to getting you up north to Valleyo. On you phone, click the Google Maps icon:
In the white box at the top of the screen, type in the address (or just valleyo, CA) you want to navigate to. The map will show a satelite image of the city with a red pin. Touch the pin. A blue and white overlay will appear. On the top right is a car icon. It is in a circle that rises above the top of the overlay. Tap that. It will come up with another dialog showing your location above the bar and your destination below the bar.
Below that is more options, which will let you choose routes that avoid tolls, highways, and ferries. Select what you would like or leave it blank if you aren't concerned. Once you are done, at the top right of the screen there are three vertical dots. Tap that and you can choose "Save offline map." This will let you navigate without using your cell data or needing a connection.
