The easiest and cheapest way to do it is to take JR the whole way. Go from Shinjuku to Tokyo via the Chuo Line (about 13 minutes), then take a VERY long walk within the station (it will take between 5 and 10 minutes to make the transfer) to the Keiyo Line platform and ride that directly to Maihama (somewhere between 15 and 17 minutes)
That's the cheapest way but it's not the easiest way. As I noted above, the easiest way is to take the Rinkai line from Shinjuku to the end of the line at Shin-Kiba and then have a very easy transfer to the Keiyo line for two stops to Maihama. The Rinkai line ride is longer but probably the trip takes about the same total time since you eliminate the long walk.
Yurakcho line to Shin-Kiba would also work but requires an additional transfer since it doesn't pass through Shinjuku.
I think the walk at Tokyo station from Chuo line to Keiyo line is more like 10-15 minutes.
