EPEVER software for programming - Solar Station Monitor - has a 'li-battery' default that is a good starting point. There are a number of threads here on adjusting from there to get what you want that works for your particular system.
Settings are only 'great' when they work for you. Each system is a little different, has different needs and requirements.
Yes, you need the proprietary cable to connect to a laptop/PC.
FLA settings tend to have too high of boost charge voltage, and tend to not terminate charging when the battery is full. And no 'equalization' for lifepo4. At least your BMS should have temp-control if you have any risk of freezing temps.
