Module development and code questions

I wanting to insert a banner on the top of a story, like where the title is..

Lets say I have 2 topic lists

Topic List 1
Banner 1
Banner 2 *
Banner 3

Topic List 2

So lets say I select the one with the *'s

I want to hard code this to use the one in topic one as the banner, so I will code

Hello,

I writing a module to allow Drupal to interact with an ASP I use for advocacy campaigns (where individuals send emails to elected officials). The ASP authenticates users via an HTTP POST and returns a cookie, allowing users to browse to any advocacy page and have the fields prepopulated (name, address, etc).

What I want to know is this.

Which hooks are called by module name and which are called by node name?

By which I mean, if I define multiple node types within a module using hook_node_info(), e.g

function theatre_node_info() {
  return array('show' => array('name' => t('show'), 'base' => 'show'),
    'venue' => array('name' => t('venue'), 'base' => 'venue'));
}

but the module is called theatre.module.

I was trying to add a payment order payment method to the e-commerce API but I can't find documentation explaining how to display information to a store administrator. Is there perhapse a hook that can be used? I'm interested in adding the information to the table at admin/store/search and store/transaction/edit/#.

Thanks for the help,

Paul

I am using drupal 4.7.0 beta3, gallery 2.0.2 and gallery 4.6.0 module for drupal.

The Gallery works fine, but when I activate the module and I go to administer -> settings -> gallery, I receive the following error:

Fatal error: Call to undefined function: form_textfield() in /home/www/cartoon/public_html/modules/gallery/gallery.module on line 36

Does anyone know how I can fix that?

Hey,

I'm needing a module (or preferably a patch to the image module) that augments the automatic thumnail creation to allow for multiple classes of thumbnails (based on node type). I haven't posted here much and I'm not quite sure what the protocol for patch submission is... As long as I'm not reinventing the wheel I plan to make this patch and submit it back here.

More specs:
