Customizing styles in Joomla blog layout

Hi,

I'm having some difficulties customizing articles in blog layout:

1) In every article there is an aside tag that, although is empty, creates a line space between the article title and the text. The original blog articles consist of title and text only, with no extras whatsoever. How to prevent this tag to be outputed?

2) Where can I control what classes should be applied -- if any -- to h1, h2, etc.? In what file are the definitions to joomla layouts and T3 corresponding classes?

Below is an example of the layout blog page code, with classes applied to titles and the aside tag. I'm using Joomla 3.1.1, T3 Blank 1.2.5 and T3 Framework 1.2.6.


Thank you for any help you can provide in this situation.
