Module development and code questions

Hi there, I could not find any documentation on logging conventions for module development. How do people do logging (debug, etc) and where do the logs get written?

Thanks!

Hey,
I've installed Drupal 5.2 a short while ago, and am busy porting my website onto the system, which is going surprisingly well. Anyway, there is one thing that I am stuck on, and I can't figure out an elegant solution to this problem:

I have a form on my website, where users get to fill in some data and furthermore, select an (infinite) number of items out of a long list. It's not a shopping cart, but that might be a useful way to think of it, basically, I have two lists, one containing items a user has selected, together with two input fields per item, specifying say colour and quantity. The other list contains all remaining items, without any further input fields. I have written a Javascript to basically transfer items from one list to the other, simply by clicking on them.

(Furthermore, I have a small text input field above the right list to narrow down choice by regexp matching the contents of that list against the text in this field. - I don't think this should matter too much for my problem)

Well, if the form is submitted, I want to store all the items in the left list together with the values assigned in their respective two fields in a database table [and delete all those items from the table that were moved from the left to the right].

I'm trying to write a filter to select and parse all my headings.

I've looked at the code for the table of contents module which is selecting only <h2></h2> and <h3></h2>, so I need to adapt it. I've got the following so far:

I have built a very simplistic module that reads from an included array to display a page that "houses" a flash application. This was done to business requirements BTW. So I was able to build the menu items, the block items and the permissions. However, I am confused at how, and if, I can get a comments section to the page. I looked through the API and other documentation to see if it is possible to get a comments section on this page, since it does not have a node ID (as it is not really a "node" module). But I can not see where or how I can get this to work.

My be I am jsut missing it but I can find the place to change the color of my nice menus I can get the borders to change but not the color of the middle part. I have changed ever color in the nice_menu.css and played a little in the style.css. I also used firebug but it did not tell me. Here is the site http://www.fansportsunion.com/
can some one point me in the right area?
Also how can I change the color of the font in the nice menu?

I need to override the number of nodes displayed per the taxonomy/term/xx page. What I'm doing now is manually editing the pager_query function within the taxonomy_select_nodes() function of the taxonomy.module.

<?php
$result = pager_query($sql, 16, 0, $sql_count);
?>

So, if we are on a taxonomy/term/xx page that has a term id of a specific content type, I want to display 16 nodes as opposed to the setting within the admin section.
