With the Naniwa set, you would need something more to set bevels, but if you're not buying off ebay you may not need a bevel setter. I have found that most NOS razors and new Dovo's (this does not apply to new TI's I've tried, and I've not tried any other new razors) don't need to see a bevel setter - you can start on the 5k.
You will need something to lap either set. I like the DMTC for lapping, and it's cheaper in the long run than sandpaper.
