"I live in New York and am looking to do a RTW which includes Bangkok-Singapore-Oz-NZ. I need to go as cheaply as possible. Do you think OneWorld is the way to go?"
If you can get a cheap ticket to London, Qantas offers a couple of useful fares. One is their Discovery Fare and the other is their Voyager fare. Both have a 29,000 mile limit, allow travel on BA or QF flight numbers (including codeshares) and a maximum of 6 stops , of which 3 can be in Australia/New Zealand. It also allows travel on CX within Asia The main difference between the 2 is that the Discovery is booked in M class (M*DISCOV) and the Voyager in H class (H*DISCOV).
In May the fares are $1622 for the discovery (MLDISCOV) and $1822 for the voyager (HLVOY).
With your straightforward requirements, these would seem to be better value for you, plus if you are concerned about FF mileage accrual, M and H are better classes to be booked in than L.
"Where can I find a website that actually lets me plan the trip thru OneWorld?"
Not really. If you download the OW timetable from the AA site, that will allow you to plan a route. The programme can be obtained at
www.aa.com , then select travel information and download the oneworld electronic timetable
