Theres a few parallels with my site (my thread below on Yahoo v google) ranking. Mine came back to life suddenly on google yesterday, having been nowhere, and now i have my pages on pages 2 onwards for our main google search term. But it definately prefers the inner pages, unlike Yahoo which ranks the index page.
For my case, most of what people will really want to know is on the inner pages, but the home page is a better intro to the site IMO. I think what Ill do is, develop the home page but also work with how it is ranking and make sure that on the inner pages that come up higher, that there is a sentence or two to orient the visitor if they should arrive there first. My site also has a menu on each page, so you can go from anywhere to anywhere.
