Answer 1

You could limit the number of columns in your query (not SELECT * ...). You've put the <input> inside the <label>. The <label>'s for="" attribute is hardcoded as chk1. You could take out the inline style="" on the <li> and put it into a stylesheet. I've "tidied" it up a bit (untested):
$womenlist = mysql_query("select * from tbl_cycleduraion where user_id=$_SESSION[user_id]");
$gs = 0;
while( $girlslist = mysql_fetch_array($womenlist) )
{
$gs++;
echo '<li style="background-color:#CCC; width:150px;">'
. '<label for="chk' . $gs . '">' . $girlslist['calName'] . ' ' . $girlslist['calDesc'] . '</label>'
. '<input type="checkbox" name="chk_' . $gs . '" id="chk' . $gs . '" value="' . $girlslist['calName'] . '"
. (($_REQUEST['chk_'.$gs]==$girlslist['calName']) ? 'checked="checked"' : '') . '></li>';
}

Not sure entirely what you're asking for here (as it looks like you already have this working with checkboxes), but you can in fact post multiple values with a select box. You just use the multiple attribute, and specify the name as an array with the square brackets:
<form action="yourscript.php" method="post">
<select name="women[]" multiple="multiple">
<option value="woman1_name">Woman 1</option>
<option value="woman2_name">Woman 2</option>
<option value="woman3_name">Woman 3</option>
</select>
<input type="submit" />
</form>
If you post a form with this, selecting woman 2 & 3, var_dump($_POST); yields:
array(1) {
["women"]=>
array(2) {
[0]=>
string(11) "woman2_name"
[1]=>
string(11) "woman3_name"
}
}
Alternatively, if you want the values of your checkboxes to come through in a similar fashion, change them so they all have the same name, but with the square brackets on the end. This HTML would yield similar POST data:
<input type="checkbox" name="women[]" value="Woman 1" />
<input type="checkbox" name="women[]" value="Woman 2" />
<input type="checkbox" name="women[]" value="Woman 3" />
So, to create a dropdown using this, here's an adaptation of your code. I believe this is what you're after:
<?php
$options = '';
$womenlist=mysql_query("select * from tbl_cycleduraion where user_id=$_SESSION[user_id]");
while($woman=mysql_fetch_array($womenlist)) {
$options .= '<option value="'.$woman['calName'].'"'.((!empty($_REQUEST) && in_array($woman['calName'],$_REQUEST['women'])) ? ' selected="selected"' : '').'>'.$woman['calName'].' '.$woman['calDesc'].'</option>';
}
?>
<label for="women">Women:</label>
<select id="women" name="women[]" multiple="multiple">
<?php echo $options; ?>
</select>
