This walkthrough includes most of the Co8 stuff. Of course, the pack was just recently updated so there might be some new stuff added since then. But it's a start. http://www.sorcerers.net/Games/ToEE/Walkthrough/index.php
Normal walkthroughs should work fine for 90% of the content, but obviously there will be missing quests and areas. Generally as far as I remember the temple itself doesn't change too much in Co8 structurewise, it's just the surrounding areas.
