"Misclicking with units stacked can be very painful " Yes, it's just asking for trouble when turn times are still short and misclicks are particularly consequential. I speak from painful experience. (Don't think there is a generic answer to how much to group units. It's situation specific. I move all units individually early in the game.)
Concur with working of stone, promotion of axes, trading of deer, and continuing play.
If cat damage is indeed only 4% per turn (BtS is surely different), then agree with Htadus that we need to go ahead and attack without further bombardment and mainly with collateral-damage-promoted cats (at least up to the point where withdrawal is a reasonable possibility) once units are all in place.
