RSS Problems in Google Reader

Firstly I had the problem of not getting full posts in Google Reader and only excerpts.

I did the following:

1) Made sure that “full text” was checked in Options>Reading
2) Corrected the code on rss2.php line 37 to read:
<description><![CDATA[<?php the_content() ?>]]></description>
3) And finally downloaded the plug-in Full Text Feed

Here are my problems:

1) The following links work fine but display different dates in Google Reader – None of which are the actual post dates. In fact the posts all have the same dates, which are different on each feed (weird!!):

http://www.darrenmusic.com/feed/rdf/
http://www.darrenmusic.com/feed/rss2/
http://www.darrenmusic.com/feed/atom/

I have no idea why Google Reader is not getting the correct post date for each individual post. Any suggestions?

2) The rss1 link eg. http://www.darrenmusic.com/feed/rss/ still does not display the full post in the reader. Moreover this also seems to be the default rss feed if one clicks on the rss feed symbol in the browser address bar (in Firefox) even though in the header.php template I see that it reads
<link rel="alternate" type="application/rss+xml" title="<?php bloginfo('name'); ?> RSS Feed" href="<?php bloginfo('rss2_url'); ?>" />
For some reason the rss2_url parameter is not pointing to the rss2.php file. Where is this parameter stored and how can it be changed? At present I have had to hard-code into the header the rss2 link.

If anyone can throw any light on these strange behaviors it would be much appreciated.

Thanks
