This is the best book there is on the subject. This link brings you to the author's sight. You can also buy it from Midway or Amazon.

It is not cheap, but it is the best. It is a complete gunsmithing guide for S&W revolvers, covering everything from simple disassembly to complex smithing.
As far as tools are concerned, I have a pretty complete set of Brownells Magna-Tip screwdrivers that I use for all my gun work.

The only speciaized tool I use to take a S&W revolver apart is this one. Removing the rebound slide spring from a S&W revolver is the trickiest part, and this makes it a little bit easier.

I have used the Wolff spring kits in S&W revolvers, they work fine. But mostly I take old Smiths apart to clean out decades of old gunk. I often find that a complete teardown and clean up is all an old Smith needs to get it working well again.
Yes, use proper fitting screwdrivers, and do not pry the side plate off. The Kuhnhuasen book shows you the proper way to remove a side plate.
