All of these points are well spent, I feel (aside from Totemic Focus, that is)

.. but what do I do with the last five points? Do I max out Improved Lightning Shield and give myself four points in Flurry? Or do I give myself five points in Reverberation and reduce my shock timer to five seconds? Also, which setup is better for duels?

I have to go now so I'll go more indepth later, but I will say that 5 second shock cooldowns are your friend. Reverberation I believe it is, and you have all the pre-reqs.

Personally speaking, elemental-specced shamans give my priest a much harder time in duels than restoration or tri-specced shamans do.  And it's not just a harder time, it's WTF 2/3 of my life is gone in the blink of the eye.  While tri-specced shamans only beat me a 'majority' of the time, they're probably better overall duelers.  But in actual group pvp, I think I would prefer having the elemental shaman with me because they can wtfpwn somebody right away and give you the 5v4 advantage before the Alliance's superior defensive abilities wear your group out.
