Yes, Thursday still works for me, and I think the earlier start makes the rest of the day easier.
If you want, bring the notebook with the larger pages because it is better for making a list that everyone can read.
Also, for snacks, I would keep it simple with fruit, crackers, and something warm if the kitchen is free.
I can handle the reminders, but send me the final names before noon so I do not leave anyone out.
About the chairs, moving them the night before is probably smarter since the hallway gets crowded in the morning.
If Dana is joining, ask whether she prefers the window side because she mentioned the room felt stuffy last time.
I do not think we need printed copies if everyone brings a pen, though one extra page would still help.
For the color labels, blue was clearer than green, so I would stick with blue again.

I would make the pasta first and leave the sauce until closer to dinner so the herbs stay bright.
If your pan is small, cook the mushrooms in two rounds because crowding them makes everything soft instead of browned.
For timing, ten minutes to prep is enough if the vegetables are washed ahead of time.
I can bring the wooden spoon and the larger bowl since that always helps when someone is trying to toss salad quickly.
If you want the table to feel less busy, skip the extra plates and just put the serving dishes in the center.
About music, keep it low at the start so everyone can actually hear each other while people arrive.
The lighter napkins looked better with the green cups, so I would probably use those again.
And yes, texting me when you start cooking is fine, because then I can leave at the right time without guessing.
