Module development and code questions

I am looking for a bibliography module that maintains a bibliography comprising of books and papers.
Each bibliography will item could have the following attributes:
Title, Author, URL , Abstract, Publication Location, Publisher, Publication Date, Volume, Issue, Pages and notes

I want to display the entries in a tabular format and allow the users to sort on title, authos, publication date, and
date added.

I want a button in the form like this (not a submit button but a button type button):

<input class="form-submit" name="op" value="New" type="button">

I use this code:

 $form['New'] = array(
  '#type' => 'button',
  '#value' => t('New'),
  '#weight' => 19,
);

....but I obtain a submit button like this:

I'm trying to modify the display of my event calednar in list form to include the location. My PHP knowledge is very limited, but I'm trying to use "$node->event_location" to call up the location using this line:

  $output .= '<div class="location">'. t('Location') .': '. $node->event_location ."</div>\n";

This brings up "Location :" in the listing, but nothing more. I'm using the event module with flexinode and I'm at a loss as to what string I need to call up to display the location.

I know several people have been looking for a module that allows single sign-on for these two apps. Just ran across a post at coppermine.net that has some help:

I was reading on this site that someone had made some php changes to the Book Review module, for the following functions:

thumbnailing images on the "teaser" page

aligning the book stats (pages, publisher, ISBN #, all those kinds of data) on the right of the larger image inside the actual review.

I am looking around for this functionality but unfortunately can't find it anywhere. Does anyone know of a patch or update for bookreview that will allow this? Or can someone tell me how to do that in php (I don't really know much php unfortunately)

Thanks!

If anyone wants a look.
You'll find it over here

... following on from last months discussions I still seem to have no CVS account so I gotta go it alone.
