What everyone has said above. I'm not going to comment on the salary thing - that's a personal judgement call.

But the most important piece of advice I can give you is simply to KNOW YOUR SHIT.
If you know the job back to front, and are good at it, and can convince them you can do it well for them, then they're either going to employ you or make a big mistake.
If you know someone else in the company who might know about the job you're applying for, try and sus them out to get an idea of the exact nature of the work. If they have any problems, think of a few solutions for them. If you know people doing that particular job at another company, suss them out too - find out in detail what they do and see if there are any differences that might work at the company you're applying for.
Wow them with your brilliance!
Relax, and be yourself - don't try putting on airs or pretending you're somehting you're not. For one thing, they'll see through it, and if not you'll find yourself in a job that probably won't suit you.

Good luck! Let us know how it goes mate!
