Berserker & Pablosan -
Beyond making adjustments in Tools > Tabbed Products Config (if you are using the Admin versin of TPL) there are instructions in the readme (readme_tabbed.html) and other docs included in the Tabbed Products mod package which illustrate techniques on how to position and move around content/objects, above and below the tabs. Also there are a number of posts in this thread describing such techniques (yes it is a long thread... and I see I didn't help much in that department).
If you want to move things around from the default settings you will want to become comfortable with editing the structure of your product_info template page (tpl_product_info_display.php) and try out moving content blocks around. The file itself well documents the various code blocks.
I do agree moving different things around on to different tabs can be a bit more complex (but with custom features comes complexity). Understanding the structure of both tpl_tabbed_products_lite.php and tpl_tabbed_products_lite_subtabs.php helps in understanding how and which content/objects are postioned on and within the tabs.
And of course don't forget the CSS (the default is stylesheet_tablitev3_silver.css).
