You need to use the WordPress’ the_time() function to output the date in the format you want. Read more about it here: http://codex.wordpress.org/Function_Reference/the_time.
Also, please understand that I cannot help you with every single modification that you want to do, since I’m doing this voluntarily and I don’t exactly have a lot of free time. This forum is intended primarily for users of the theme who encounters technical problem with the theme, not to help people do custom modification to the theme to suit their needs. For that, I do accept paid freelance work to do the modifications for you.
Also, please consider donating to help support the theme’s support and development.
