Ideally, it might be best to get tickets before the lodging reservation but even though the ticket sales begin on Oct 3, you won't know until later this year or early next year exactly which events you got tickets for.
In my case, I felt it was best to secure the lodging now and work on the tickets later this month. The events I am most interested in seeing are not ones that will sell out quickly. And based on past experience, event tickets are often available even during the games. Lodging is generally much more at a premium than event tickets.
