Here are the scripts for data management and publishing that were shown during the Pacific User Conference Plenary on Monday, 13 October 2014: http://www.arcgis.com/home/item.html?id=f31ad687d7b443eaa4696536024c6ddc
Please give these a try, adapt them to your workflows, improve them, and share the improved scripts with the community!
Script 8 (Register and Share with ArcGIS Online) requires ArcREST v1: Esri/ArcREST at October2014v1.0Final · GitHub - if you'd like some practice working with ArcREST, see if you can figure out how to create thumbnails for items registered with ArcGIS Online. Share your code in the comments!
Thanks to Scott Moore for his help with these!
