Shamelessly desperate plea for help!

Hello, sorry I’ve posted some of this before however I’ve gotten no response, so I’m trying again.

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

2) 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!
