Nagini venom

Hi everyone,
Does anyone else wonder about Nagini.  I presume she is Voldemort's 
Fawkes, but she only materialised recently as far as we know, whilst 
LV was in the forests after CoS.  The only reference to mythology 
around her name I can find is about a woman (the Dragon King's 
daughter) who achieved instant Buddhahood by sacrificing her life. 
(http://www.khandro.net/mysterious_nagini.htm)

There are some questions about Nagini which I find quite interesting:

1) In OotF St Mungo's Hospital (p416 British ed) DD looks at the 
smoke and says: "In essence divided" and the smoke splits into two 
snakes.  Do we assume that LV possessed Nagini and they both went to 
MoM, and that's the two snakes.  Or is it referring to LV and Harry?

2) The wound which Mr Weasley gets from the venom doesn't want to 
heal, something in it keeps the wound open.  This is the same venom 
which LV uses in his potion to keep him alive (along with unicorn 
blood).  Could there be some connection here with how LV is 
vanquished - he bleeds to death maybe (although I do favour my other 
theory about the room in the DoM see  my message 106591)

3) Why have a Nagini?

I look forward to all your thoughts ....
