Leia: Visions, they were on Cartoon Network but I was very young
Luke: I have no memory of the Clone Wars
I noticed that if you are into EU, you are more apt to like the Clone Wars Series. Personally I could never get into them, because I hate when Lucas has to include something interesting that he didn't have time to put in the prequel movies. But he can spend the first hour of TPM developing Jar Jar. It is one more reason why the prequels get my blood boiling when I think about them.
To me, it would have been if Lucas made a cartoon of Luke training on Dagoabah cause he didn't have time to put it in ESB.
