"How to Organize an LLC in North Carolina" or "How to Incorporate In South Dakota", and "How to Start Your First Business" etc, etc. There are plenty of books that deal with the nitty gritty, nuts and bolts stuff, taxes, naming, etc. Just to spend an hour or so at a bookstore and poke around.
As for specific recommendations... I'd have to get out of bed and go dig through my stacks of books to pick some out, but one that comes to mind is The Art of the Start by Guy Kawasaki. Not quite down at the level of "how to deal with taxes" etc., but some good low-level stuff about launching a startup.
Also, if/when you go to B&N (or Books-a-Million, whatever), somewhere near the "small business" section you'll usually find a section with the accounting/finance/taxes books. You'll probably see a few titles like "Tax Handbook for your Maine LLC" etc.
There are also books full of "stock" forms and contracts and what-not.
Also, if you have a community college nearby, you might call them and see if they have a "small business center" of some sort. That's pretty common here in NC... they offer seminars and sessions periodically, on topics like you are asking about.
You might also see if your state (assuming you're in the US) has something analogous to CED (the Council for Entrepreneurial Development) that we have here in NC. http://www.cednc.org I'm guessing most states have something similar, but it might be called something different.
Finally, look into SCORE - the Service Corps of Retired Executives. You can hook up with a retired exec who can provide some mentoring and assistance to you.
