Hello,
You can change the image on the shop page in the page settings: https://xtemos.com/docs/woodmart/options-for-pages/
By default the categories pages inherit the shop page settings, if you want to set different images for categories, enter each category and set the image: https://xtemos.com/docs/woodmart/product-category-menu/
You can change the font by means of the Advanced typography option, which allows you to choose the item from a drop-down or insert your custom CSS class. Please navigate to the Theme Settings > Typography > Advanced Typography.
Here is the documentation providing more detailed instructions: https://xtemos.com/docs/woodmart/advanced-typography-settings/
If you have any questions please feel free to contact us.
Best Regards
