I use
http://feeddigest.com for consolidating feeds. It gives me a chunk of code I can put on my blog. I subscribed to their pay service so I could manage more feeds, but they have a free one as well.
If you are using MS Office 2007, the latest version of Outlook can manage feeds for you. You can subscribe to the feed manually, or automatically through IE 7 and the feeds show up in your Inbox.
