Shit, I'm sorry I missed your message entirely. I was actually planning on messaging you a few weeks ago and seeing if you wanted any assistance. I'm super interested in your hack.
The naming screen graphics are located at a/0/3/1. It took me a while to find them myself for some reason. I can also give you a list of every other location of the player character's occurrences. The palette file is 1_1.RLCN. The file is 1_10.bin. And the palette numbers for Ethan, Lyra, and the rival are 4, 5, and 7 respectively.
As for the GameFreak logo, I'll have to look into my files. I'm working till midnight tonight, and I go in at eight in the morning tomorrow till around three in the afternoon, so after that I can help. I'm on EST by the way.
A couple of guys from /r/PokemonROMHacks set up a Discord server. We can chat there and I can use Discord to send you any files you need.

I've also been setting up a tutorial for the rest of the introduction sequence. It's on hold till the next version of Tinke, or until I find out if a certain feature will be present. If Tinke's update has a proper image map editor, like they've demonstrated in their issues section, it'll render my entire tutorial moot. And the tutorial is fairly deep, relying a lot on hex editing.
Here's a demo for that:

I'll be on Discord on my phone all night, so you can hit me up and I'll respond.
