One other random bit of advice. Lightroom makes it easy for you to convert from "native" raw files to Adobe's DNG format. Do not do this. Keep everything in its original format. This gives you more flexibility later. For example, the authors of Bibble are adamant that they won't support converted DNG files. They do, however, somewhat interoperate with Adobe's xmp "sidecar" files which Lightroom writes out next to your raw files, to hold all the metadata you add.
