Seems like Leafs don't have plans to bring up many (if any) new kids this year with the FA signing they have made. Marlies will have a very young, talented roster though.
With Komarov recent struggles with the law this is what I'm seeing for the Leafs up front;
JVR-Kadri-PAP
Panik-Bozak-Lupul
Bailey-Arcobello-Holland
Spaling-Winnik-Leipsic
Bailey and Leipsic are rookies, so those are the two new guys that would make your team. Additionnally, the next forwards in line are realistically Marner, Nylander, Kapanen and Gauthier, so unless Toronto signs more UFAs or promotes some career AHLers, yes Toronto will have a bunch of new rookies in their lineup.
