Mohs to nose - how is it healing up
It is way to soon to tell. It really can take up to 6 months to see how everything will resolve after a Mohs procedure like you had done, which was very extensive. Corrective things can be done later, and yes, injections can be done to alleviate the lumpiness of the scar. But it cannot be done too quickly. The body needs time to fix itself on its own before we go in and try to do other things.

Healing following flap reconstruction
It will take time for the wound to heal well. In the first few days after surgery a splint could help to support the nasal structure. In any case, it could need a small revision down the road.
