Hello, You will be very happy with your Williams by Bachmann purchase.
O27 is the smallest rails in O 3rail hobby(except for superstreets). So this train set will run on Lionel O27 track and Standard O which is O31minimum curve. You can run it on any curve of that size or bigger from any of the manufactures of 3rail O gauge track. Note though that O27 has a lower profile to the rails.
In fact, here is a link that explains some of this:
http://www.lionel.com/ForTheHobbyist/AboutGauge/ I know this is a Bachmann forum but that link explains it well for a beginner.
You may want to check the OGR Forum...there are a lot of guys there that have built these ceiling layouts using all kinds of supports.
Good luck to you and welcome to the hobby
