I have a little question about your 1st problem:
Is that menu opened via some command?


And answer for question 2:

You can make it to set players skin randomly from few specified skins:

pawn Код:

new Skins[] = {282, 283, 284}; //you can change these skin IDs and add more if you like

pawn Код:

new rand = random(sizeof(Skins));
SetPlayerSkin(playerid, Skins[rand]);
