changing pagination on HOME page

[giuly]

Hello I bought a template because it has many characteristics I need, for example it is created a

personalized in which there are images and slides and other.

So I have
header.tpl with
[code]

{$HOOK_TOP}

<!-- Left -->


<!-- Center -->
{if $page_name!='index'}

{/if}
{if $page_name=='index'}

{/if}
{/if}[/code]

and footer with
[code] {if !$content_only}

<!-- Right -->
{if $page_name!= 'index'}

{$HOOK_RIGHT_COLUMN}

{/if}

<!-- Footer -->

{$HOOK_FOOTER}

{/if}
</body>
</html>[/code]

I would modify this aspect and have 2 columns, so left and right and center at start of home page, then I need that it remains the center_column_home

I have tried to add left column on header.tpl
adding
[code]

{$HOOK_LEFT_COLUMN}

[/code]
and it is ok I see on left blocks.

If I add something like [code]

{$HOOK_RIGHT_COLUMN}

[/code]
on footer.tpl instead I see right categories but on the bottom of index page so not at the start like left column, but after center_column_home.

Where have I to modify?

Sorry for my english I hope you can understand what I wrote.
Thanks
