help needed for Opera, wallpaper, ringer

[iclickjohn]

I have Adryneline's M2D Rom, But these are general questions.
I hate that thing that is on the screen of Opera that shows where you are scrolling. I've searched literally everywhere including opera:settings/website/forums/etc. to get rid of that. Or find a recent version that doesn't have it. This is the #1 thing I want to change the most since it blocks your view of the website as you are scrolling.
Wallpaper. I want to change the ugly grid wallpaper used by HTC in M2D. But it won't let me paste over the existing one in windows. I've made a few that I like and they are in "my storage" in a folder, my file has the same name as the default wallpaper. I have it for the today screen because that is selectable. I am talking about the rest of the backgrounds when you scroll sideways.
I want to put my "OldPhone" ringer back into this ROM and need to know if it needs to be a certain file type and where to place it. (I may not need the answer to this as I plan to put it in a few spots that seem obvious) Thanks.
