The Killing Quandry -- Prophesy Related

I'm a bit (OK, more than a bit) fuzzy on what would happen if someone 
other than Harry killed Voldemort or someone other than Voldemort 
killed Harry. Could Quirrell have killed Harry without Voldemort 
being in him?

On another post, in response to one of my questons, someone suggested 
that DD hasn't killed Voldemort because he may fear that will also 
harm/kill Harry, which makes perfect since, because Harry has Voldy 
bits in him due to whatever happened to cause the scar and whatever 
connection they have due to their wands locking.

But Voldy has Harry's blood in him, and yet, the reverse doesn't seem 
to be true, meaning it doesn't seem that Voldemort thinks he would be 
harmed/killed if someone else kills Harry.  Voldemort entered Harry 
in OOP in order to get DD to try to kill Harry, but even if DD had 
killed Harry, I don't believe it would have killed Voldemort.  He 
doesn't seem to be the suicidal type.  Of course, he may just be 
wrong since he doesn't know the full prophesy.

Speaking of which, the prophecy says that either must die at the hand 
of the other for neither can live while the other survives. While I 
believe that either Harry will kill Voldemort or vice versa, I don't 
see why the prophecy must mean that ONLY Harry can kill Voldemort or 
that ONLY Voldemort can kill Harry.  (No one's going to convince me 
that DD couldn't kill Voldemort or Harry.) Could the prophesy simply 
mean that neither Harry nor Voldemort will truly "live" until the 
other is dead?

For the sake of discussion, if it is the case that only Harry can 
kill Voldemort and vice versa, was that so before their wands locked 
in GOF?  If it wasn't so before GOF, then it seems the locking of the 
wands is an unprophesied part of the prophesy (unless the locking of 
the wands was marking Harry as Voldemort's equal?) 

Hope this babbling makes sense.  I'm feeling rather Yogi Berra today.
