10 degree blocks, two shims back.
Pretty good place to start.
Also build it with all the lubes and oils that come in the kit. Will work great then you can adjust.
I tried the 5 deg blocks a few times and never liked them but it depends on the class your running ect.
Stock oils, stock springs, 0.5mm front droop 1.5 rear. About a degree of camber/toe and watch the tires.
Unfortunate about the box mixup and broken stuff, fortunate that crc stuff is everywhere and very cheap while you wait for replies.
Ps get the shock extender.. makes pod droop adjustment very nice and eliminates dependance on those super small ballcups
