Regarding your first question, you need to modify a template file:

Before doing any modifications, backup your initial file.
In skin/Island_Bangles/customer/content.tpl template file you add an additional condition clause in the line referring to the 'customer/bread_crumbs.tpl' file, ie:

Look for the code similar to:

{if $main neq "catalog" or $current_category.category neq ""}            
   {include file="customer/bread_crumbs.tpl"}
{/if}

and change it to :

{if $main neq "catalog" or $current_category.category neq "" or $main neq "help"}            
    {include file="customer/bread_crumbs.tpl"}
{/if}
