Module development and code questions

Hello all.

I have a database on news article and want to create a simple module that can list all the titles and there publication date. Since there will be thousands of article, I am planning to show titles of only 10 news article at a time and include "next 10" and "prev 10". I am not sure how can I maintain the current value and decide which button was clicked. Below is the code of what I am up to. Particularly look at getOutput() function. I have two questions
1. Am I doing right or there is better way to do this
2. Currently my code is not working properly. What might be the reason

<?php
// help section
function viewer_help($section) {
$output = '';
switch ($section) {

return $output;
}

function viewer_block($op = 'list', $delta = 0, $edit = array()) {

$block[0]['info'] = t('Quick Browse');
break;

case 'view':
$block['subject'] = t('Quick Browse');
$block['content'] = getOutput();
break;
}
return $block;
}

function getOutput() {
$value = 0;
if(isset($_POST['index'])) $value = $_POST['index'];
$form = '

Anyone working on this? If not, perhaps I can find some spare time this summer to adapt.

Hello everybody,
I am trying to customize the user profile template by cleaning up some of the fields.

All our users' data is populated via the ldap_integration module, and I'm trying to condense values such as Address, City, Zip, State, etc. into a single field instead of having a page of separate fields.

Current profile display is:

I'm developing a module and I'm looking for the simplest way to check to see if a particular file exists within Drupal's 'files' directory. This is probably a no-brainer for many of you out there.
