New to Necromunda - Where to Start

[AvePicante]

GW Dragged their feet on the Votann release, and I was desperate for some new Dwarves. So, I ended up with a set of Ironhead Squat Prospectors, a pair of the Scout Trikes and a Vartijan Exo Driller. These models are beautiful, needless to say I'm hooked.

 

What would I need to start playing? I see on the store there's the Book of the Outlands and the Halls of the Ancients book. Would both of these alongside the core rule book be necessary for the Squats? I have a lead on one single person at a game shop in my area who runs Necromunda in Central Florida, but our schedules haven't aligned.  I've played about a dozen games of Combat Patrol, and a handful of 2k games with Combat Patrol rules, so I'm not totally new but still inexperienced.

 

Thanks for the help!
