Its good for you to use sscanf and zcmd, they will organize better your command, you just gotta search for some tutorials, now about the /commands you can either show a menu or a message:

Message:

pawn Код:

if(strcmp("/commands", cmdtext, true, 10) == 0)
   {
      SendClientMessage(playerid, COLOR_BLUE, "-----Server Commands-----");
      SendClientMessage(playerid, COLOR_BLUE, "/heal , /help, /kill");
      return 1;
   }

Dialog(Menu)

pawn Код:

if(strcmp("/commands", cmdtext, true, 10) == 0)
    {
      ShowPlayerDialog(playerid, 1, DIALOG_STYLE_MSGBOX, "Commands:", "/heal, /kill, /heal", "Ok", "");
      return 1;
    }

its good to define some colors to use later
put this on top of your script:

pawn Код:

#define COLOR_BLUE 0x0000FFFF

Hope i helped
