WP_Query with pages

HI. I’m building a site where we’d like to show a summary of 5 specific pages (not posts) on the home page. Sort of like a sub menu (there’s a main nav menu at the page top as well created with wp_list_pages()). Normally I’d just use wp_list_pages() and include the required pages as a parameter. But…rather than just a list of links we’d like to show the Page Excerpt (using Peter Westwood’s PJW Page Excerpt allowing me to add excerpts to a page) as well as a thumbnail added using a Custom Field. I’ve seen how to do this with posts or to pull the Custom Fields for the current page but not seen it like this for pages.
Regards, Edward
