Best thing to do is to keep a record of all the questions you are asked and watch for patterns. If you see the same question coming up frequently, make sure you write a FAQ which covers it.
Every company is different and position themselves in particular markets. The FAQ's of a cheapie host are different to those of a host that deals mainly with businesses, and hosts whose customers are from one geographical location will get different questions to some host in another location.
Even with hosts who run the same control panels (like cPanel, for eg) the questions will be different. You can still save yourself support time, however, by writing a "how to" for every feature offered in the control panel.

I was actaully going to make a list of questions not only for my business but i was going to refer to this post, and make a somewhat big index of common questions that are asked by people on these forums. This will provide a place where new hosts can get a feel for questions that will be asked.
There was a website that had this exact list that I am trying to compile, and i remember it helped me alot when i was new with support.
