I'm planning to replace two of the three windows in my top floor with a new casement window that's 40 inches wide and 30 inches tall. I'm wondering if I need to brace the wall or roof during this process. If bracing is necessary, how far from the window should I set up a temporary 2x4 wall?

It sounds like a good idea to check out the drywall on that whole wall first. By removing it, you'll get a clear look at how the studs and top plate are set up. This could help you figure out how to mimic that support further back. Some folks might suggest putting a big post in the middle for extra support since that area will bear the most weight during the window swap. I'm interested to see what advice others can offer too!
Just a heads up, since you're only swapping two window frames for one, consider keeping the existing header over the windows. You could install the new window lower to reduce stress on the wall.
