Customers seem to ask questions regarding every little thing
Are these questions answered on your web site? (presuming yes.) Then this could mean that your vision of how easy that is to find is not as easy as you thought. True though, often people don't bother to look and just send the email, no matter how easy it is.
One approach is as you said, a contact form but with a twist - set it up so it does a post via Ajax for the terms as they type them, and if results are found, a section appears: "Do these links answer your question?"
Personally I agree with others, these aren't annoyances, they are leads.
