There are a few websites that offer help with learning Burmese. So far most of them don't extend beyond an elementary level - a few phrases and some introductory observations. The most developed is the site set up by U Saw Tun at Northern Illinois University: http://www.seasite.niu.edu/Burmese/Default.htm
Cornell University's Language Resource Center has a site with some helpful tips for practicing writing and naming Burmese consonant letters, prepared by San San Hnin Tun. See http://lrc.cornell.edu/asian/courses/bu/materials/scriptanime.
