I do not know your skill level, or how ambitious you are, but the "reshaping" to get rid of the nicks, dents and cuts is something you can do before sending it in for refinishing. All it takes is a few different files and progressively finer grit sandpapers. Caution and some skill will be needed around the roll marks but it might come out good enough (if you decide to do the entire job) that you won't have to sent it in. From your pic's nothing looks so bad that it could not be made to look great again. After refinishing it should look good again, however the dimensions will always be slightly different than Factory because some metal will be lost in the process.

If you are not up for doing it yourself, call Smith and ask them exactly what they will do to the metal prior to refinishing. There are other refinishers too - like Fords. I would hope that a professional refinishing outfit would make it look like new again but will obviously cost much more.
