Does the unused coordinate positions in the array have to be filled with obsolete coordinates if they are outside of the bounds of the setStripVertexCounts(...)?

I don't think you can resize the total, allowable vertex count of the strip array. But, if you make the initial geometry array large enough (i.e. set to a known maximum) at construction, you can then use setStripVertexCounts to set the current valid strip counts.
