Yes, there are compilations of all the study FAR's, remember that pilot ATP study materials are the same as the FD license requirements. Shop online and you'll find what you need, but there is much available for free off FAA websites- 'seek and you shall find'

The above are (at least were when I did it) required study. Others who have done the license more recently than me may wish to correct me or add more. You should know in the States that these documents are not subject to copyright and are free to the public, however, many one that you can buy are straight copies of the above. The quality may be a tad lacking on some of these .pdf files- but the above is a significant start on your road to the license.
And EMA747, if you are asking a question like 'can I take the exam online' you've not done your homework yet. Contact Sheffield and I am sure they'll give you all you need to know.
