Honestly having played just the tutorial and a bit more, I think most of everything should be autopilot and not too hands on with Yellow.
I do suggest concentrating on expansion and nest digging (not too deep, as rain raises the water level), once a patch is available.
This would mean that adjusting the worker/breeder/soldier ratios are the first thing to do, and pressing the ‘mating’ button in the overview.
It looks like (in my full game) the doghouse is where the reds have their ‘stronghold’, so expanding there might be rather tough if you choose to go straight at them.
Otherwise, just relax and enjoy, I don’t think this was ever meant to be a ‘war’ sim.
Also, the in-game tutorials and guides seem good.
