Easier Navigation?

I have begun adding in very basic navigation links at the bottom of each story post in an effort to make it easier for new readers to find their way around and for existing readers to skim through previous episodes, should they wish to.

At the moment that means a 'Next Episode' and 'Previous Episode' link at the bottom of every episode post (where appropriate) and, as a bit of a further trial, a 'First Episode' and a 'Full Episode Archive' link (in addition to the link in the home bar at the top) have been added to the most recent episode, 'Dawn Raid' in case these might also make overall navigation easier.  The 'Next' and 'Previous' links will skip out any News posts, so they should not interrupt your reading experience.

Please, let me know what you think.  It's all very basic, so if you know of an easy to use script which will work in Blogger and do the same thing, that would also be great.
