Hi,
First, when you edit your menu item via the Joomla menus manager, under the "products options" tab you have settings to customize the display of the listing. There, you'll find an option to display only the taxed price and not both.
Then, if you want to change the order of the elements and place the name before the image instead of after, you can edit the file "listing_img_title" of the view "product" via the menu Display>Views and swap the different blocks of code.
And lastly, if you want to change the size/color of a text, you can add custom CSS to HikaShop.
Regarding these 2 last points, I invite you to read this tutorial which explains how to customize the CSS of HikaShop, and how to customize the view files of HikaShop:
