As far as basic common settings.
Some negative camber on the front wheels. (better turn in)
Less negative camber on the rears than the fronts, if any at all. (larger contact area while drifting, better throttle authority)
Some toe in on the rear wheels. (keeps the tail of the car in check somewhat)
Generally lower the car quite a bit. (improves all around response)
Past that it's really all preference. Do you want a car that initiates drifts easily? Understeers to allow more aggressive wheel work mid drift? Has very high steering authority but requires more delicate control in the drift? It mostly has to do with the balance between your front and read rate settings and swaybars.
Honestly if you're just learning though, don't worry about all that. Drive stock for a while to get a feel for the car and drifting in general, then make those few alignment changes (don't go too extreme with them though) and feel the difference in them. Then change one thing at a time until that's comfortable for you.
Personally, I don't like to spend a ton of time tuning, so I tend to just adapt and go as far as I can with a particular setting until I notice something real obvious to me that I want to change.
I doubt there's many people with the Caterham here, so it looks like you're gonna have to make them up yourself!
