Can someone make sense of this?

In this theme the title/logo is an image, which means you will need an image editor to add your own text. You can do this by opening the blank logo image located at Photoshop Files/logo_blank.gif, or by opening the logo PSD file located at Photoshop Files/logo.psd. Replace the edited logo with the old logo by placing it in the following directory: theme/eNews/images. If you need more room, or would like to edit the logo further, you can always do so by opening the original fully layered PSD file located at Photoshop Files/eNews.psd

Can someone help me undertand what it is I have to do please?

I am trying to change the logo/title of my wordpress blog in a new theme but things like:
"You can do this by opening the blank logo image located at Photoshop Files/logo_blank.gif" -Where is that?:confused:

"or by opening the logo PSD file located at Photoshop Files/logo.psd" -I can't find that either?:confused:

"Replace the edited logo with the old logo by placing it in the following directory: theme/eNews/images." -Maybe I'm just really tired? :confused:

"If you need more room, or would like to edit the logo further, you can always do so by opening the original fully layered PSD file located at Photoshop Files/eNews.psd" -I think I will need to, when I understand what it says:confused:

Can anyone help me please?

P.S. I have looked in my ftp but can't find any of these. Nor can I find any of them in theme editor in dashboard.
