A easy first step would be to look at Aualex website and look at what they market as studio accoustic 'kits'.
You will see they mostly consist of strategic patches near the monitors . some for side walls and corner 'bass traps'.

Start there and embark on a accoustics learning journey...
Either get a kit, or learn how to do it yourself, but at the risk of sounding like a 'nag', the old 'foam everywhere' route - is the road to audio ruin!
Good luck!
