I did this for an old folding bike that I have. I used a Shimano 333 hub instead of a Sturmey-Archer AW because the Shimano is 36-hole hub (probably the most common drilling #).
For the rim, I unlaced a 20" alloy rim from a girl's bike that had a coaster brake hub in it. I reused all of the spokes and nipples and laced in the Shimano 333 hub. I ran the cable all the way down from the shifter to the chainstay fulcrum clip. So, all of this ended up being relatively cheap in terms of cash but costly in terms of time and luck (finding all of these things).
The spoke length was around 7.25", and I have heard this is generally the right spoke length for lacing 36 hole Sturmey Archer hubs to 20" wheels.
I'd double check the following:
1. the dropout spacing on your bike is 110mm (if the dropout spacing is greater then you may need a longer axle on your hub or you will have to cold set the frame)
2. the dropout size (the slot for the axle) needs to be big enough for the axle.
3. make sure the anti-rotation washers fit in the dropout
P.S. I took the coaster brake hub and laced that into a 26" rim. If you're lucky the coaster brake hub will be the same size as your 3-speed hub allowing you to reuse the spokes and nipples.
