Facebook seems so needlessly complicated

My sister dragged into Facebook last winter, and I'm on it, begrudgingly...but I was intrigued at FB for business, although after taking 5 times to set up a fan page, it seems SO friggin complicated!

If anyone can offer insight into the following issues, I would be SO thankful!

Seriously...THANK YOU!

1) Do you have a FB page for your BUSINESS? Is it a fan page or a group?

2) Have you considered signing your business up as a separate person? (I think it's against FB's TOS, but I'm not sure...and it certainly doesn't mean that we don't know people who have done it)

3) This friday, 12 June, FB is introducing usernames (finally!) do you know if they're offering it for businesses?

4) How in heck can you find businesses through FB? I can't find an easy search ANYWHERE. I always have to go to help and through several different links to find where I can search businesses.

5) Is there an app that will allow you to update your FB BUSINESS page and twitter at the same time? I know they exist to update personal FB accounts, but nothing for updating the status on a fan page.

6) How do you promote your business FB page? There doesn't seem to be any way to do it within facebook other than to ask your friends to become fans. Is that how we're supposed to drive traffic? Just ask people we know, and then hope that they'll tell people they know?

7) How the heck do you get it to appear that you're a fan of a business on your main page? The only way that people would know that I'm a fan of, well, me, is if they go to my info and see my "pages."

8) Can a business (fan page) become a fan of another business? I'm having business associates who want to "friend" me, but my personal FB account is personal. They don't need to see if my cousin or prom date thinks I'm "hot or not." (I am, by the way, but I digress...) So I want to reciprocate, but can't quite figure out how to do that.

Thanks again for your help!!! Frankly, I like twitter better for business because I can add other people to my stream, or block 'em or whatever, but people think I'm weird for not having a FB page, so there you go...
