In the hot seat
Let me back up ZRH on his statements. In general you'll be warmly welcomed in Switzerland. You will certainly find those that are a bit xenophobic, but I guess this hold true anywhere in the world. After about a half a year you'll be checked and current and on your daily grind.
One thing you don’t have to worry about is the salary. You'll be taxed at the source while you hold a B permit. At any rate, you'll be able to afford a rather decent lifestyle with your family and as single even more so. After some time, 5 Years I believe you'll be eligible to apply for a C permit (Green Card) at which time you'll be taxed just as anybody else.
As it is the Canton that issues the permit, you may be required to stay within the same Canton where you work. Again, with some time you'll be more free to move around as you want.
Hope that helps.
Good luck
