Once you have your google account set up using Adwords Editor, you can do a bulk upload to Yahoo. It works slick. Save out your file to Excel. Save it as a unicode text file, but name is a .csv (just a little quirck). Then to go Yahoo and import file using their Import tool - it will put all keywords, ads, ad groups and bids together like your Google account.
Good luck
