I'm not sure if you are posting at the right sections for your questions. You see, Abilities
do not exist in Generation I and II games.
However, you may check your Pokemon's stats and moves through simply pressing 'start' to load the menu and move the cursor to 'Pokemon' and press 'A button'. After that, simply check the Pokemon by moving the cursor to the right name and press 'A button'. If you need to quit the screens, the 'B button' is always there for you to press.

The Third Generation forums, which houses FireRed and LeafGreen, the Kanto remakes for the GBA platform.

The Rom hacking section can be huge and confusing, so I strongly advise you to ask the moderators of that section for more assistance.
If you need further assistance on the games feel free to ask me questions. As for the forum stuff, it is better to leave them to the staff, haha. Hope that helps! (:
