Hi karmyn -- there's a lot of info about Myst, and it's a bit difficult to know where to begin.
Chronologically, I think that Myst Uru: Complete Chronicles would fit in after Myst IV: Revelation and before Myst V: End of Ages -- though I've seen arguments that it actually comes chronologically after Myst V.
Myst Uru has many 3D worlds or ages to explore, involves puzzles that I would mostly describe as mechanical or movement puzzles. There's brief character interaction, but mostly you are exploring and figuring out what happened to the ancient race of the D'ni.
