The deal with Dolly is in fact true. She is aging at a much increased rate. The skinny of it is this: There are certain genetic markers in human DNA that tells the body when to start aging. Werner Syndrome is an example of what happens when this gets f*ed up. There is still much research to be done before cloning a human could possibly be of any benefit. Not to mention all the ethical issues that arise. (and legal ones, as well)
