No idea what they mean by "tar" either, but as long as your sd card is partitioned then you won't have to do it again and that's where your programs should get loaded to instead of internally to the phone to save you some space on the phone. If I was you I wouldn't worry about it, if you have your sd card partitioned and your rom is up and running like you want then things are good to go, if not I would just flash the rom you want and start over, but that's how I would do it, nothing like a fresh rom running on the phone.
