A quick summery which would be a good starting point
Front castor i think i run 6 degrees was a little while since i measured it and cannot find my setup sheet
1.5 degrees negative all round
2mm toe in on each wheel on the front
2mm toe in on each wheel on the rear, but parallel is great fun for throttle controlled steering, start with 2mm toe in to start and slowly creep up on the parallel as its not to everyones liking. under no circumstances have toe out on the rear as this will be lethal and massive roll oversteer.
Make sure you bushes are good and no play etc as a Coupe will get very nervous if there is play/give especially on the rear.
Tyre pressures
20 front
24 rear a good starting point its what i currently run.
Also worth checking for bump steer when you get time but with the above set up there should be minimum to zero on the rear allowing for different tolerances on peoples cars etc if your using the locking bars, as these only work effectively for one camber/toe setting venture too far away and it all starts to go wrong.
I have tried 2 degrees negative on the rear but have now gone back to 1.7 as a happy compromise for my preffereed style
