Hi.
Just my two cents on your questions:
1 - Check your local code provisions for the maximum seismic acceleration to consider and multiply it by the equipment mass. You'll get the seismic force that you can distribute easily by the equipment's supports (usually standing on rails, right?;
2 - The volume of the pit beneath the transformer should be able to receive the entire oil volume of the equipment plus a safety margin for additional water that may enter the pit (+10% of the total oil volume, for example). You should check with the equipment supplier for this information.
Regarding the pit slope, I guess that 1% or 2% should be sufficient, but check with the supplier again.
Hope it helped.
