Well you are approaching this the right way getting as much info as you can give it time & it will come. Take any suggestions as ideas though this is not an RTS game with obvious winning tactics, there is no one road to victory path rather loads of diffrent tactics depending on many factors & as you develop you will learn more. Hard game to master if you ever trully do you will get the basics down pretty quick then a couple of years later you will be playing diffrently because you have developed.
Remember just like you are doing here one of your most powerful tools is infomation so use those scouts & gather it. Patience can be a virtue to just because you can start fighting if delaying one turn gets extra forces involved it might be worth it, decisive blows cost a lot less men than drawn out firefights.
