That first HIVE tool I linked to tells who commented on my latest post but didn't vote for it.

As for me seeing which comments I voted for, that is on my Replies page, so no tool required. So I can see there which comments I have already up voted and which I have not. But sometimes I'm low on vote power and I don't vote my posts' comments in that case.
