Sam, Per Ted's email below please run with the trunk for your work. Please look at Chapters 13 - 16 in the Mahout in Action book for sample code snippets for classifying 20 newsgroups with SGD. There presently is no command line option (I am not aware of one and could be wrong) for running the 20 newsgroup example with SGD.
The only command line tools for SGD - trainlogistic and runlogistic expect the input files to be in CSV format which is not what you have. I have a sample program for qualifying datasets (similar to the format you have) using SGD which I can share with you later today.

The bayes classifiers are designed for large data. Poor results are not very surprising at this data size.
