That's ok Brian, i made one by myself with your firts idea!
I am sharing that piece of code so it could help someone...
/// If you add this code to the item_details.tpl it will navigate you to other items of profile owner.
//Captures for Nest & Previous Links:
{capture name="template" assign="next_tpl"}
{literal}
{jrCore_module_url module="myModule" assign="murl"}
{foreach $_items as $item}
<a href='{$jamroom_url}/{$item.profile_url}/{$murl}/{$item._item_id}'>Next</a>
{/foreach}
{/literal}
{/capture}
{capture name="template" assign="prev_tpl"}
{literal}
{jrCore_module_url module="myModule" assign="murl"}
{foreach $_items as $item}
<a href='{$jamroom_url}/{$item.profile_url}/{$murl}/{$item._item_id}'>Previous</a>
{/foreach}
{/literal}
{/capture}
// If items ordered to new to old in item_list next one actually will be older one. If you are using another method to order items you can change order_by and search parameters
{jrCore_list module="jrGenStory" order_by="_item_id numerical_desc" profile_id="`$item._profile_id`" search1="_item_id < `$item._item_id`" limit="1" template=$next_tpl assign="next_link"}
{jrCore_list module="jrGenStory" order_by="_item_id numerical_asc" profile_id="`$item._profile_id`" search1="_item_id > `$item._item_id`" limit="1" template=$prev_tpl assign="prev_link"}
<div class="nextprev">
<div style="float:right;">
{$next_link}
</div>
<div style="float:left;">
{$prev_link}
</div>
</div>
