Joe,

I think that it would be best to split it into a limited number of simple categories that would all displayed on one screen (800x640 is probably a reasonable minimum nowdays)

If I was writing it, I'd put up some generic titles with a bit of explanation underneath. ie:

About Mudcat
(The whys and wherefores of this site)

Finding Lyrics
(How best to find what you want)

The Digital Tradition
(what it is and how it works)

Mudcat Culture
(what is BS and suchlike)

Membership
(Cookies, PMs etc explained)

Technology
(How to make links etc)

The above are just off the top of my head, so may not be suitable, and there are doubtless more.

In each section, I would then have a list of answers to the most common questions (some would obviously be listed in more than one category, but that's OK). That's how I'd do it anyway...

Hope the above makes sense and is of some use to you.
