Good afternoon and congratulations.
I cannot help you with the skid swap. Carbs are straight forward - clean them out, new jets, new needle and seat and she should be good to go. Normally no need for a bowl gasket unless the existing one is damaged. Just about any shop, New Breed, Dennis Kirk, Pats Small Engine etc. can get you going with jets.
Use the oil injection. The oil pumps are great and vary the oil with rpm. And, if the pump fails, the only result is over oiling, not under oiling.
