I think that the bear was actually named Clarkie bear in the series, but I don't know where it turns up. The bear found its way to Lois in GGGoH, that I know for sure. When its name is mentioned I cannot say, though.
Regarding "CJ" for Lois' and Clark's oldest son - I know of one series where Luthor manages to create a perfect Clone of Clark, and Lois and Clark then adopt the clone baby and call him CJ. (Nan Smith' Dagger Series). There is also a whole next-gen series where Lois and Clark's second son is named Samuel Clark, but everyone calls him CJ. (I don't remember the name of the series, but its last installment is "Meet Sam Wayne".)
