Checking if sound/sprite exists before passing it to precache would be nice. Use file_exists for that. In case of wrong configuration, make some logs to notify the user.

I don't think that is necessary. It would be obvious if a file is missing. A message will show in the console if a sound is missing, and the server will automatically crash if the sprite is missing. In addition, file_exists checks in the cstrike folder, and people may use sounds from the valve folder.

When replacing the old sounds/sprites you could unprecache the new ones(just a matter to hook FM_PrecacheModel for sprites and check the sprite name, for sounds hook FM_PrecacheSound). I assume you know default names for sounds & sprites.

I did it for the sound, but I'm not replacing any sprites.

In grenade_throw check if user is alive before retrieving team.

Are you sure about this? What if the player dies in the exact moment when he is about to throw the grenade? What's the problem of getting the team of a dead player?

Everything else is fixed.
