This will be my very first Starfinder game. I've played plenty of Pathfinder first edition but I've not even read the Starfinder CRB. I'm planning to read through as much of the CRB as I can before PaizoCon but maybe you guys can give me a bit of advice on where to start.

I would suggest reading the tactical rules chapter. That is where the heaviest of the content is. After that, the starship combat section of the Starships chapter. Once you are familiar with those things, everything else should make sense from there.
