what size spur gear would i need for a 6000kv ezrun in this buggy

stop your fixation on spur gears. You can run the kit spur in any car, it's the pinion gear you need to alter. Just get yourself a range of 48 dp pinions from 17-23 and then you can alter your ratios easily and go up or down a tooth on the pinion depending on motor, track layout, car etc

does it need a slipper clutch to stop the main driveshaft from breaking

For the Ezrun 5.5t you'll want 18, 19 and 20. 20 works for fast flowing tracks, but needs 30C Lipos to get decent punch, 19 is an all rounder and 18 works well indoors or on very tight tracks.
The standard spur is the only size I've seen!
