Copy the entire wpbook directory into your wordpress plugins folder,
/wp-content/plugins/
You should have a directory structure like this (of course you'll likely have different plugins installed):
Set up a New Application at http://www.facebook.com/developers/, obtaining a secret and API key. You can use the following image (click for full size) to see an example of all the fields on the "Basic" tab in Facebook:
I believe the icon, logo, user support address, and bookmark url are all optional, but it might be a good idea to fill them out.
On the "Authentication" tab, check both "Users" and "Facebook Pages" if you intend to make any use of the functions associated with Pages, or just "Users" if you only want users to be able to add to profile. (If in doubt, check both).
On the "Profiles" tab: set the Tab Name to something that represents your blog. In the tab url section, put: ?app_tab=true&fb_force_mode=fbml
On the "Canvas" tab: Set the canvas callback url to your blog url, including a trailing slash. (Example: http://www.yourblogurl.com/)
For canvas url, you just need something all lower case, unique, with no spaces, and no trailing slash.
Set the application to use an iFrame, not fbml, and to "resizable" NOT "smart size." Set "Canvas Width" to full width.
On the "Connect" tab, set the connect url to your WordPress site url, including a trailing slash. (Example: http://www.yourblogurl.com/
). I don't believe the account preview URL is required; if yu set it, use the url of your Facebook application (as shown).
For the "Widgets" and "Advanced" and "Migrations" tabs, you should be able to accept the defaults, but just in case:
Login to Wordpress Admin and activate the plugin
Using the WPBook menu, (Dashboard->Settings->WPBook) fill in the appropriate information including Facebook application secret, API key, and canvas url.
After you've filled in the required settings, jump to the bottom of the page and hit "save" to save your settings.
That's It!
You should now be able to visit your Facebook application's URL (it will look something like http://apps.facebook.com/openparenthesis/
, with the "openparenthesis" part replaced with whatever you provided on the "Canvas" tab in Facebook, under the setting titled "Canvas Page URL"

In addition to the required settings, there are many potential customizations for WPBook. Most of these are found in the WPBook Settings page in WordPress, under the heading "Customize Facebook Application View" and are described below. NOTE: These are optional, and defaults should be fine for most users.
These options all have to do with commenting from inside your Facebook application view. That is, they do not apply to Facebook comments made in response to excerpts posted on your FB wall, but only when users are veiwing the full text of a blog post inside your FB application, at a url like: http://apps.facebook.com/yourcanvaspageurl/2010/01/page-slug/
(your permalink url appended to your facebook app url).
These options have to do with the template for views inside the Facebook app.
These options control how WPBook deals with pages in your WordPress site, in the Facebook application view.
More options which apply to the Facebook Application view
These are hidden under the "Show Advanced Options" checkbox - checking that will reveal them.
