Yes mate. Add up the weight of all the accessories you intend to fit (not just the ones you have now) and use that calculation to select your spring rate.

Helluva lot cheaper going the 2inch spring lift and a 2inch body lift as to what drewboy mentioned you need. No point going a 4inch lift if you can do a body lift and cut the cost by a fair bit IMO.
Plus it would need to be engineered for the 4" lift and 35" tyres.
Could end up being expensive
With body lifts, I have read that it cracks the mounts over time?
I want to build the car to handle the cape, any other things susp wise will I need?
As Drew points out, there's a few things to think about. I would definitely go with the same front and rear estimating your weight first. You can always adjust ride height a little by using coil spacers once it's all set up. If you decide on a body lift there pro's and con's but don't forget you will have to change all your bar work to fit properly. Mounts can crack, Nylon is better as it gives a little flex and is still strong and if your mounts are in good nick you should be fine. As Drew points out there are roadworthy issues in Vic too to think about.
If 35" tires are used do you reckon the differential gears should be modified?
