Modding quotes and loading screens

1. I've changed the tga files in the loading_screen folder but I can't change the logo from Rome Total War to the one I want for the mod. Is there a way of modding so that the name of the mod appears there instead, or do CA want you to keep the RTW logo even in mods? I have no problem with that, it's just that I'd prefer a specific loading screen for the mod. When I change loading_overlays.tga it only displays the part of the text that lies inside the pixels forming the text Rome total war. I've tried changing loading_logo_and_bar.tga to same but the problem remains. Temporarily I'm keeping the RTW logo but am using a different loading bar loading screens for the background.

2. My second question is for modding quotes. A Medieval mod with ancient quotes looks bad IMO. I'd like to change them in case I find enough interesting quotes, or just remove quotes altogether. Has anyone deciphered the files and does anyone know how to remove all quotes or how to change them all. I want a different number of quotes and I want to know how quote author is connected to quote and how quote translations are connected to quotes etc. This isn't extremely important but I think it'd add a nice touch to the mod I'm making.

I think that the quotes are in /data/text/quotes.txt or a similar file, anyway, the file is in the /text/ folder

the parts of the quote are linked by a numbering system: {quote_1}Vae Victus {author_1}lkdsajflkjasd'lf

or something like that. The sturcture is really pretty simple once you look at the right files

I have looked at the files but the structure seems complicated. It's not like quote_1 has author_1 etc., or so it seemed to me.

Data\menu\textures\FE_texture1.tga has the R:TW logo text.
FE_texture4.tga has the "TM" that appears with it on the menu screen.

Relevant files for loading screen quotes are:
Data\descr_transition_screen.txt
Data\descr_quotes_lookup.txt
Data\text\quotes.txt
