Fall Stocked YP at 8"-10" long will definitely spawn the next spring assuming they have a maintenance diet late fall and overwinter. Often 6"-8" long female perch are capable of spawning. Well fed YP will go into winter with enough body fat to finish egg development for the spring spawn. Midwestern and northern yellow perch start egg development in August.
I would add SMB after you verify that you had a perch spawn in spring. Presence of YOY perch takes some of the SMB predation pressure off the minnows/shiners/invertebreates.
