I was trying to find the contextual help section for all the admin pages so I could add some additional text. The main pages I need to hit are the "Pages" page and the "Widgets" page but I'm not sure where to find the files for these. Anybody know file names where I can find the contextual help?
Do NOT edit core files! You can add to or override the default text by using a filter. Try taking a look at http://justintadlock.com/archives/2011/06/02/adding-contextual-help-to-plugin-and-theme-admin-pages
