Excellent post and exactly something I needed...except for one thing -> the onchange in the form provided in post #2 gave this error: "document.product_per_page_form has no properties"

So instead of
onchange="javascript: document.product_per_page_form.submit();"
I used
onchange="this.form.submit()"
which fixes the problem

I then stripped out the unnecessary name attribute in the form tag and the all option (since that would have been overkill for me), and added an id so I could apply styles:

<form method="POST" action="/change_ppp.php" id="pppForm">
    Show products per page
    <select name="ppp" onchange="this.form.submit()">
    <option value="12" {if $products_per_page eq 10}selected{/if}>12</option>
    <option value="20" {if $products_per_page eq 20}selected{/if}>20</option>
    <option value="30" {if $products_per_page eq 30}selected{/if}>30</option>
    <option value="50" {if $products_per_page eq 50}selected{/if}>50</option>
    <option value="75" {if $products_per_page eq 75}selected{/if}>75</option>
    <option value="100" {if $products_per_page eq 100}selected{/if}>100</option>
    </select>
</form>

I successfully tested it in PC Firefox & IE7, Mac Firefox & Safari. You can see it in action here: http://www.shopbettylin.com/home.php?cat=249
