No supporting electronics are needed, the hall effect end-stop boards plug directly into RAMPS (or whatever electronics you are using). Source: [www.reprapdiscount.com]
The idler is just two regular bearings, size 624 as shown in RichRap's part two blog:

Make up three sets of Idler bearings for the Spectra line, try to use the same type of domed bolt, washer each side (not in between the bearings) an M4 nut and M4 penny or M5 washer - if you do that it will also grip the printed cover cap nicely. - The bearings are 2 x 624ZZ types (13mm outside and a 4mm hole) you can use whatever size fits, but I doubt 608's will work and won't fit under the printed cover cap.
