A clarification:
Lightroom does NOT import images nor does it move them around by it's own violition.
LR "import" looks at the image on the harddrive, copies the image to its own preview database, copies the Exif data to its own database, makes an entry into its database as to location of the image and compiles all that information into a Lightroom Catalogue. Any changes you make to the location of an image, providing it is completed within the Lightroom environment, is recorded in the database.
If an image is moved in the Operating System (Windows = Explorer, Mac = ?????) the changed location is not recorded in Lightroom. When you try to open an image in LR which has been moved in the OS, the image will show as the Lightroom preview, but that image cannot be processed because LR does not know where you have moved it to, thus the "missing image" messages.
If you make alterations to an image in LR, the catalogue will record those changes. The original image as stored on the hardrive is untouched. So in Ligtroom, you can edit and crop to your hearts content, but if you open the image in Picassa or Irfanview or whatever other graphics program you have, those edits you did in Lightroom will not be there. The originals are not altered.
If the originals are jpg or tiffs, all the changes are stored in the LR catalogue, if the images are raw files, the changes are stored in xmp sidecar files.
If you move a raw file (by means other than within Lightroom), and forget to move the xmp file with the picture file, then your changes may be lost on your harddrive and you could end up in a bit of a pickle, especially if you have moved many images.
Always move images within Lightroom
Always backup your catalogue
Always export finished images if you want to work on them in a program not linked to Lightroom.
If you install Lightroom you are installing the means to manage your images, hundreds or thousands of your pictures can be located, catalogued, named, put into collections (albums), even geotagged, but remember Lightroom is forgiving and can be also forgetfull.

When I use LR to make changes to an image, I use the Export command (Ctrl-Shift-E in Windows) and save it to a different folder than where the original is located. If I were to export it to the same folder and use the same file name, it would replace the original image, right?
