Is Harry really in trouble?

In GoF, Voldemort's and Harry's wands do not work well against each 
other as they come from the same element.  

If Voldemort was revived from Harry's blood, wouldn't that mean that 
attacking Harry would not do Voldemort any good?  

Doesn't Voldemort in essence owe Harry a life debt?

I believe I read somewhere that JKR was asked about Harry's life 
after Hogwarts, and she said something like "What makes you think he 
lives?"  Wouldn't it make sense that Harry would have to sacrifice 
his life to make Voldemort vulnerable?

I know these are not original thoughts, as I have had very few of 
those in my life, but I cannot find an answer to them.

Looking for some commentary
