The second book (Streets of Laredo) in publication order is the fourth book for internal chronology. It follows on with Call from the first book (Lonesome Dove) and is a more natural transition from Lonesome Dove.
The third book (Dead Man's Walk) loops us back to young Call and Gus days and the fourth (Comanche Moon) follows that to lead somewhat into Lonesome Dove.
I think starting with Lonesome Dove is the right move as it's the one that gives the best connection to the characters and provides the launchpad for the other stories to deepen the story lines and strengthen reader connection.
