In principle we need only one (make that two, in case MM is not perfect

) irrigated grass and the banana to be shared between the two cities.
Then 2 cottages and that's all we can work with our current happiness level

.
So I think we don't need more workers currently.
Something just coming to my mind

, don't connect the copper immediately with both workers, send one chopping. Otherwise the warriors change to spears and will not complete according to my evil plans.
Later the workers should team up to get at least one irrigation in place fast. One of them them leading before the settler after that to have the road on gold already done.
I think settler should be build in Erkopper, immediately following the warrior. Change to copper with 1 turn to grow. Then the warrior should complete with growth and we even get a bit of overflow into the settler. Then switch to copper and banana.
MW building granary next. As we grow slow anyway, while EK has the nanas, we might want to hand build it working the last forest also. But we could also pop-rush shortly before completion and put the overflow in a barracks, as there's probably time for an axe or 2 before sailing.
So now, LC, you can work my gut feeling plans into a real plan with spreadsheet and all, if you like.
