I'll try to provide a simple but understandable explanation on how to install all the files. Unlike other mods, I skipped some files because they are basically non-essential  and caused bugs in CTGP-R (like the text files).

| Award |
The file inside this folder should be installed inside Award.szs with CTools. Keep in mind that there are two Award.szs files in the game, one for models during the award ceremony, and one for character icons. To install it, open the Award.szs that contains the models, search for the file called ca.brres, and replace it with the file inside the Award folder. Here are the steps numbered:
1. Open Award.szs (the one containing models/brres files) with CTools (SZS Explorer).
2. Search for ca.brres (Which stands for Catherine, which is Birdo's name I think).
3. Right-Click and replace.
4. Select the ca_award.brres file inside the Award folder.
5. Save.
6. Done

| Icons |
This takes a while. You will need SZS Modifier to install both icons, and the files MenuSingle.szs, MenuMulti.szs and Race.szs, which contain character icons.
Open any of the files with SZS Modifier, and in the treeview expand the timg folder. Search for Birdo's icon, double click on the displayed image and replace it with Tails' icon. Keep doing this process for all of Birdo's icons, there may be a total of three icons depending on which file you are editing. Here are the steps numbered:
1. Open MenuSingle/MenuMulti/Race.szs with SZS Modifier.
2. Expand the timg folder.
3. Search for Birdo's icons (tt_catherine_64x64.tpl, there are more than one on each file).
4. Double click on the displayed icon.
5. Click on File>Import>Select the corresponding Tails icon.
6. Save.
7. Repeat steps 3-6 Until you're sure there are no more icons for Birdo.
8. Save (I'd recommend "Saving as" instead of overwriting).

| Menu |
This folder contains three files, for the SZS Files simply drag and drop the files into your SD card, but for the brres files you will need to use SZS Explorer. Basically you need to follow the same steps as in the Award section, but you will edit the Driver.szs instead. Driver.szs contains the characters for the character selection screen. Open Driver.szs with SZS Explorer, find ca.brres and replace with  the ca_select.brres inside this folder.

| Sound |
This is definitely the hardest part, but it shouldn't take long. To install Tails' voice clips you will need Brawlbox (I recommend v0.71, don't ask why) and a revo_kart.brsar, which contains the sounds for the whole game. In BrawlBox, open your revo_kart.brsar, there should be a list with different files. Search for the files with the IDs that this folder has(for example search for the file with the index number or ID 13), open them, and replace the Audio[n] files with the files inside the folder with the same number. It's quite hard to explain, but once you understand it should become easier.
1. Open Brawlbox.
2. Open your revo_kart.brsar.
3. Search for the file with the ID number 13.
4. Double-Click.
4. Right-Click on Audio[0].
5. Replace.
6. Search inside the folder with the ID 13 the Audio[0] file.
7. Repeat steps 4-6 but with Audio[1], Audio[2], Audio[n]..., if there are more.
8. Save and exit the file (not the revo_kart, but the ID file).
9. Repeat steps 3-8 but with the other IDs (83, 173, 288, etc.)

| Vehicles |
For these files, follow there steps carefully:
1. Copy all the files inside this folder.
2. Paste them in your SD card (MyStuff if using CTGP-R).
