marketpress default product list style product name too big

marketpress default product list style with product name too big.

Is it possible to reduce the text in the product name, the price, and to adjust the add to cart button style?

please see screenshot.

Is it possible to have and the add to cart button the white text with a blue (006dcc) button color?

where is it possible to adjust the style with CSS?
Thanks.
