You have the option to challenge the order of the division bench of the high court by filing SLP in the supreme court, if you are aggrieved by the high court order.
Since, it appears that the division bench of the high court has ordered de novo / fresh inquiry by department, the department can conduct such inquiry, unless you get the high court quashed or modified from the Supreme Court.
As regards payment of subsistence allowance during suspension, that appears to be wrong. You may go to appropriate court / tribunal for directing the department to pay the subsistence allowance.
[But, if the high court itself has stated in its order that the period of dismissal which has to be considered as under suspension, will be without any payment of subsistence allowance, then that may be a different issue, and in that case, you may have to challenge that in the supreme court.]
