This is an adaptor; you'll still need to get a BB set, and you'll want to figure out what length spindle you need before you order. There are BB sets that press into an American-style BB shell but come with a spindle, but these tend to have 125- 130mm long spindles, which will probably push the chain out to far for your application.

Is it this SRAM crank?
Or this one?
The top one is a s100 1.1 "courier"; you'll need the American-to-euro adaptor, and a 68x113mm powerspline BB set. It's GOTTA be powerspline. Square taper won't work; ISIS won't work; Octalink won't work. It's gotta be powerspline, which they only make in a few sizes, and the 113 will come closest to the usual STurmey 3-speed's chainline. Once it's all installed, there are tricks with using different spacers and rear cogs to dial in the chainline perfectly.
The bottom one is a SRAM Omnium, which usually ships with the BB. You'll need the americn-to-euro adaptor and a 68mm SRAM GXP bottom bracket; there's no different spindle options, as the spindle is part of the DS crankarm. Chainline should be decent; again, there are tricks to dial it in perfectly once installed.

Sure thing. Don't forget the adaptor. 
Once you got it all installed, check the chainline... you can use dished cogs in either direction to move the chainline in or out a few mm, or play with spacers, swap the chainring for the inner or outer position on the crank, etc. But the 113mm powerspline will get you going in the right direction.
Good luck! I think you'll enjoy the upgrade.

I am still amazed by the knowledgeable people we have here, since I only work on old bikes with old parts I could never had answered that question...
Way to go Rob !
