Im looking to start mix in sunday MTTs schedule to my weekly cashgame grind schedule

I feel like i should start by learning some fundamentals like ICM, and learning shoving and reshoving ranges. There is plenty of stuff out there on ICM (anyone who recomends me something?) but learning what the shove, when to shove, when to reshove seems something software could really help me out with. I use CREV for cashgames, i saw they also had a tournament version, but it didnt seem like it would give me the answers i wanted for EVs of shoving reshoving etc. Wich software would you guys recommend? or where would you recommend me to start? to learn some fundamentals mainly for ICM, shoving, reshoving, and shortstack play. Im not looking for exact answers or charts or anything like that, i want to know HOW to find/calculate/study the answers, and how to learn so i can improve.
