I am loading 5,000 contacts from a spreadsheet and I know that some of these contacts already exist in the current organization. Do you know if there is any application that can be used to de-dup these contacts when I am mass loading rather than having to merge them one at a time?

 

Thanks!

I'm recreating a detail page and I'm trying to add some related lists that are currently displayed on the existing page.  I'm unable to figure out what the list names are supposed to be though.  The names that are used in the pagelayout editor are not working.  Some example list are "Notes & Attachments", "Approval History", and "Activity History".  How do you find out the names to use in visual force for related lists?
