For me resolution is like u said, the drivers ability to extract musical information and present it. More resolution = drivers able to pick up stuff in the recordings, this is very similar to detail and microdetail/nuances, detail to me would be, how obvious that resolving ability is and how easily its heard, this can go from being analytical and hyperdetailed to being dull and veiled, a lack of detail in a sense. From crisp and sharp to dull blunt and subdued.
Clarity is more like transparency, how easy is it to hear the music, like an open window, how the headphones disappear and all you hear is what the artist intended, not in style but rather can you hear it all easily and well? Is there anything in the way. Do u feel like its a recording or a live performance? A headphone can lack clarity in a sense due to treble warmth and colorations, but still be transparent, like hd 650, its hard to hear some details and stuff especially in the treble. Also a lack of openness or a headphone too slow and congested can reduce clarity, clarity in a sense is everything as a whole, transparency, extension, detail, openness, naturalness, etc. transparency is more specific, how close you feel to the music. Grain, lack of detail, distortion, artifacts, lack of coherency, unnatural tones, harshness, obvious colorations, slowness and congestion, etc, i think would interfere with this.
