Using form data on a page

Hi all,
I know this issue has been addressed here and there, but I've been searching for two hours and can't find a good explanation.

I want to use two values from a form to query a database, then display the results. I know this is probably doable with Views, but I'm building this module from scratch and would like to keep it simple - I'm using external data, and custom Views coding doesn't seem fun. Anyway, the form is fine, but once it gets submitted I can't figure out how to access the data in the following page to include the values in the query. I have been fiddling with 'page arguments' in the hook_menu of the second page, but I can't figure it out.

Here's my hook_menu...

function pts_menu() {

    $items = array();

    //Menu & URL settings for the module
  $items['admin/settings/pts'] = array(
    'title' => 'PTS module settings',
    'description' => 'Settings for the PTS module',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('pts_admin'),
    'access arguments' => array('access administration pages'),
    'type' => MENU_NORMAL_ITEM,
   );

    $items['have_case'] = array(
    'title' => 'Do I have a Case?',
    'page callback' => 'have_case_all',
    'access arguments' => array('access pts content'),
    'type' => MENU_CALLBACK
  );

    $items['address_results'] = array(
     'title' => 'Address Search Details',
     'page callback' => 'address_results_all',
     'page arguments' => array('have_case_form'),
     'access arguments' => array('access pts content'),
     'type' => MENU_CALLBACK
    );

    $items['address_details'] = array(
     'title' => 'Address Details',
     'page callback' => 'address_details_all',
     'access arguments' => array('access pts content'),
     'type' => MENU_CALLBACK
    );

  return $items;
}

Here's my form...

function have_case_form($form_state) {

    $form = array(
        //'#action' => url($_POST['q'], array('query' => drupal_get_destination())),
        '#id' => 'have-case-form',
        '#submit' => array('have_case_form_submit'),
      );
      $form['house_number'] = array('#type' => 'textfield',
        '#title' => t('House Number'),
        '#maxlength' => 10,
        '#size' => 15,
        '#description' => 'Please enter only numbers, not your street name.',
        '#required' => TRUE,
      );
      $form['postal_code'] = array('#type' => 'textfield',
          '#title' => t('Postal/ZIP Code'),
          '#maxlength' => 5,
          '#description' => '5 digits only',
          '#required' => TRUE,
       );

     // $form['#multistep'] = TRUE;
     // $form['#redirect'] = FALSE;

      $form['submit'] = array('#type' => 'submit',
        '#value' => t('Submit'),
      );

     return $form;

}

function have_case_form_submit($form, &$form_state) {
    drupal_set_message(t('Form Submitted!'));
    $test = $form_state['values']['house_number'];

    drupal_set_message(t('Search for House #!'. $test));



    $form_state['redirect'] = array('address_results');
}

And here's the second page (the function I need to get the values into)...

function address_results_all($house_number, $postal_code) {
    
    //Change to PTS database
    db_set_active($name = 'pts');

  
    //Retrieve information for address with given data_id
    $result = db_query("SELECT * FROM {orps_data} WHERE orps_data_id=%d",$house_number);

    $r = db_fetch_array($result);

    $p .=$r['full_address'];


    //Reset to default database
    db_set_active($name = 'default');
    return $p;

   
}

Thanks for your help...
