Module development and code questions

I can't figure this out. I'm working with a guy on a custom module and somehow it affects all node's links. It creates a phantom link at the end of node links, like so: read more | add new comment | and that last blank is <a href=""></a>. Anyone else have a problem like this?

I have module myauth.module, that implements the _auth hook as such:

Oh dear, this turned in to a longer post than I had planned. Forgive the multiple questions all together. It seemed easier than re-explaining my project over and over...

Alright, I readily admit I'm a newbie when it comes to Drupal, PhP, and MySQL. However, after reading through the example_node.module tutorial, and related material, I felt I was ready to tackle something simple. Here's the story:

I attempted to set up a simple module called 'newsletter'. Essentially, when a user creates 'newsletter' content, they provide a volume number, issue number, etc. and then supplies various article texts for the newsletter. Ideally, the submitted content is then displayed in a nice formatted newsletter-type node based on the supplied content.

Now, following the same guidelines as the example_node.module tutorial, I created my own database table using a mySQL statement like this:

   CREATE TABLE newsletter (
     vid        int(10) unsigned NOT NULL default '0',
     nid        int(10) unsigned NOT NULL default '0',
     vvolume    int(10) NOT NULL default '0',
     vissue     int(10) NOT NULL default '0',
     vt00      longtext,
     vs00      longtext,
     vb00      longtext,
...
     PRIMARY KEY (vid, nid),
     KEY `newsletter_nid` (nid)
   )

(It turns out there are over 40 fields.) My module can successfully create a newsletter node, except...

I am trying to get a google map setup so I can enter an address into a node I created with the Content Construction Kit, I am doing this now but all by hand as I geocode the address and then add that to a .xml file that gmap loads. I want to have this automated so I can add a location with an address and drupal geocodes the adress and then takes the tittle of the post and the address and the link to the post, then puts it all into a point on the map. I have gone thru the post and have not found anything that will do this, the modules i have found will do this for users only.

I solved a common OG problem and I would like to know what others think, if it's a bad idea or not. I'm using OG for the first time so I'm not sure if what I did is a good idea.

My Drupal website has relied on Taxonomy Access Control and TAC_Lite to control permissions of forums and other content. My forums were imported from phpbb and I needed the user specific access that TAC_Lite provides.
