Could you repost that as an attachment? the wrapping applied by your email client makes it very hard to read. Just perusing it, it doesn't look like you're CPU bound, but I/O bound. As Craig mentioned, you may do better with some form of replication solution here than pg_dumps. Given that your db can fit in memory (when you say it's 8G do you mean ON DISK, or in a backup? Big diff) then the only thing the backups should be slowing down are update queries. Select queries shouldn't even notice. However, there's a LOT of wait state, and only blocks out, not really many in, so I'm guessing that you've got a fair bit of writing going on at the same time as your backups.
