business template customisation

Hello.
I very like this template.
But now I have some problems:

1) I translated the "Login" and "Reg." form, but I can`t find where to translate sentense "Log in to your account or" in Login form; and "* Required field" in Registration form.
2) How to change buutons background color (for example, from orange to black).
3) How and where (in what folder) I must insert my images in Image show module and News show pro to display my images (not Demo slide).

Thanks in advance.
