Selwa, I'm glad I could help. I suggest you import the source code in an IDE (we use Eclipse) and navigate around it. The outline view in Eclipse is a lifesaver :)
BlocksMap does not seem to have that API. I would try FSNamesystem on the namenode. On the client side, the DFSClient class is what opens a file (and takes care of all the block-mapping). Hope this helps, Ravi.
