Charlie,
First, remove the topsoil if it's in the pond basin. Store it somewhere & use it to replenish topsoil where needed such as on the dam.
Second, it's your call about the springs. If I read you correctly they are in the pond basin. If this is true they can either help or hurt, add water or take water. Most people here would play it safe & plug them.
Lastly, leaving the topsoil covering the springs will not prevent them from hurting you. If you have free flowing springs above the projected water line of the pond then it is possible you may be ok leaving them unplugged. Again, It's your call.
