P2 Custumization

Hello, I would like some further customization with this theme however I am unable to find where the html elements of the theme is. I’m only able to find functions it calls. For instance:

1) I would like to change the date format from “4:12 am on March 19, 2011” to simply March 19, 2011. However I can only locate a function that calls for echo p2_date_time_with_microformat within entry.php

2) In replying to comments, I would like to remove the email and website fields.

3) This seems to be more of an issue than customization, but the Ajax loading symbol is always present whenever a post is initiated, https://i5.photobucket.com/albums/y184/Wandera89/ajax.jpg

Any help will be greatly appreciated!
