To help automate the process a little bit, just have the PPC engine set duplicate bids for all your keywords and then change the ones you need to. It's less work than changing thousands of keywords by hand. Most keywords don't require micro-management.
I'm not positive and perhaps engaged can give you more information, but I think AdWords lets you upload spreadsheets with all the data (keywords, bids, etc).
