The dishwasher drains into the disposal. I would be tying the clothes washer below the kitchen sink/dishwasher inlet and above the bathroom inlet.
I have heard that I may need to separate the sink and dishwasher drains, creating a trap arm for the dishwasher

The dishwasher needs to go up, to an air break, before it goes down to the garbage grinder. I like the deck mount air breaks, because you can see if there is a problem. It also keeps ground garbage from back feeding into the dishwasher.

It will be ok if you do it as drawn. Assuming that vent stack is vertical.

Ok so tying in my clothes washer (3 fu) under my sink/dish washer's trap arm making a wet vent totaling 4fu above the clothes washer is going to be fine
