It's a LOT of pulling this week. Jump those pullups. If you aren't up to it, just give them a rest today. No need to sub for anything.
Those KB high Sumos should loosen up your back a bit from Monday's workout.
It's like our "Citizenship" workout, just without the team. On average, many teams did reps similar to the ones recommended above.
Pushups are standard "snaked" style.
Keep those elbows higher than your wrists on the high sumos. If your wrists are bent, it's a pretty good bet that you are putting stress on the shoulder joint.
