I would suggest the full mod spec 120A speedo, as you know it will work with what ever you throw at it.
The programming card isn't easy to answer, as it depends which card you have. If you have the older one, it can be used for both the V2 and V3 spec ESC's, but not at the same time - you have to change the firmware on the box. However, the later boxes will work with both ESC's with no changes etc.
