maybe you can find a wordpress plugin for creating a sitemap
not sure if google really needs a sitemap, cause it can just follow all internal links on your website and then it sees all pages your site consists of
i guess sitemaps help google to find a page on your website that has no link to it on your website

so reading through this here, it seems like it can be good if ur website is huge
and one guy says its good so google knows faster what new pages u added
