Cooper RF-9540NAW and RF-9500 association via Minimote

Maybe I can help myself if I clarify the actual questions:

*If I plan to use the minimote to create an association do I start with all all three devices connected to the hub? Do I need to use particular device handlers long term, excluding any short term use of tweaker.
*Should I create the association for the mains powered device with the tweaker and then create the association for the battery powered device with the minimote?
