UK-Born US Citizen Living/Working For US Company in UK

Hi,
I was born in Manchester, UK in 1978 to U.S. parents who lived/worked in the UK until 1989 when we moved back to the U.S.  I have U.S. citizenship and a U.S. passport.  Now, I'm looking to move my wife and two small children to the UK while I work for a U.S. company with a UK office.  I'm hoping to get some guidance and insight on the following questions...

1.  Is it correct that I can apply for a British passport since I was born in the UK?
2.  If so, do I need any type of visa or is the passport enough to work/live in the UK?  Would I then enter the UK with the UK passport?
3.  What about my wife?  Can she work while living in the UK?  Without a visa because she's married to a British-born husband?
4.  Would my children need visas?
5.  Is it typical for a U.S. company with UK office to pay a British passport holder in dollars or pounds?  Which is better?
6.  We would keep our home in the U.S. as an investment and rent it out but live full-time in the UK.  Any problems in doing so?
7.  It's my understanding that we would file U.S. taxes along with UK taxes but you're not double-taxed on income...is that correct?  Any further details would be greatly appreciated.     

I have loads more questions but hope this gets me started.  Many thanks for any insight.

Hi, I've already replied to your questions in your other thread in the Visas & Citizenship forum, so I won't reply here as well .

It's actually easier if you only post your questions once, in only one topic/forum, so that all your information and the advice you get is together in one place. If you've got two topics asking the same questions, you'll end up with two different sets of answers and that can get confusing as to who has replied to what and what information/advice you have been given when and by whom .
