To weigh in on the salary figure question... Isn't it, psychologically speaking, advantageous to put the first number out? And shouldn't you have a solid idea of what salary you want? So giving desired salary+5-10% seems reasonable to me...
Anecdote time:
After I graduated a year and a half ago I was pretty careless and got flown out for an interview with a company did basically no research on. It was far away and I didn't really want to live there so I just went for the experience.
So anyway at the end they asked me what I was expecting salary wise, I did my best to refuse but they said they at least needed some idea of my minimum. So I said that I wouldn't consider anything less than 50k. The HR lady kind of laughed and said "we pay more than that."
About a month later I got a call and they offered me the job with a 68k starting salary I accepted... Then about 10 minutes later she called back and said she had mixed my offer up with somebody else's and the offer was actually for 73k and hopefully I would be okay with that one instead?
I still work there, but I guess negotiating doesn't always matter?
Out of curiosity what field was this in?
