Chain of Memories shows what happens to Sora, Donald and Goofy between the ending of KH1 and the beginning of KH2. 358/2 days is about Roxas - takes place before KH2. Those two games link KH1 and KH2 together. Don't worry about Final Mix versions.
You don't have to play those two games. If you're enjoying the KH story, then you should give them a try. Otherwise don't because CoM is awful.
