My interpretation of the rules is since there is no weight limit specified for LakeTrout/Salmon waters then the 2 fish can both be state records and you can keep them both as long as they're legal length.
As far as the OCT-Dec period, it does not state that bass, pickeral, white perch, etc. are not to be taken so therefore you can fish for these. But it seems that would create a loop hole for a pseudo catch and release of salmon/trout by people "intending" to fish for other species and that doesn't seem right to me if the idea of F&G is to give the salmon/trout a break period from fishing pressure. On the other hand the bass and other species fishermen would be pretty steamed if they couldn't honestly attempt to catch those fish.
