Excellent job Graziella. Everything looks like it's shaping up nicely.
Here are some bus websites you can check.
It looks like the ADO has only two buses per day from Oaxaca to Puebla. I think UNO may only run between Oaxaca and Mexico City. Another line, Cristobal Colón's website isn't working. I would check availability for the Oaxaca-Puebla leg while in the bus station in Mexico City, then confirm that upon arrival at the bus station in Oaxaca. If it looks like it is filling up I'd make my reservations then. Of course, if you feel anxious about it go ahead and make the reservations now.
