You just need to open up theme.html and in there you will see somthing like:
<td id="centerCcolumn" colspan="2">
<!-- Start center-center blocks loop -->
<{foreach item=block from=$xoops_ccblocks}>
<{include file="default/theme_blockcenter_c.html"}>
<{/foreach}>
<!-- End center-center blocks loop -->
</td>
And a bit further down this:
<td id="centerLcolumn">
<!-- Start center-left blocks loop -->
<{foreach item=block from=$xoops_clblocks}>
<{include file="default/theme_blockcenter_l.html"}>
<{/foreach}>
<!-- End center-left blocks loop -->
</td><td id="centerRcolumn">
<!-- Start center-right blocks loop -->
<{foreach item=block from=$xoops_crblocks}>
<{include file="default/theme_blockcenter_r.html"}>
<{/foreach}>
<!-- End center-right blocks loop -->
</td>
Just swap 'em round
