That really is very stiff indeed. Front will probably be around the 700lb area but IMHO that is so far from normal that you need a suspension specialist to look at the whole car: springs, dampers, bushes, set up angles, ARB, tyres, etc.

Yes, it is vitally important to get the front and rear springs and dampers in the correct proportion to each other. You need to know what spring rates you have on the rear. You also need to assure yourself that the rear dampers are working correctly. Mixing old and new dampers is generally not a good idea because the damping characteristics varies over time, even more so if you are mixing damper brands/types.

The best way to determine the spring length is to measure the overall length of the existing dampers when the car is at its normal ride height. Work out the static spring length that will give that correct overall damper length on the new damper (or range of spring lengths if the new ones have adjustable spring seats and pick a spring length roughly in the middle of the range). Work out the static deflection, which is roughly 800 lbs divided by the spring rate. Add this to the static length to get the free length, this is the length you need to give your spring supplier.

Um, have you consulted a suspension specialist about these spring rates? This combination sounds like a rather ... unconventional ... setup.

Hmm thats strange I thought the spring rate per spring was 450 front and 500 rear or has someone been feeding me the wrong info ?

Joking aside you really are talking about some odd numbers. Nice car BTW.

Ok thanks for the email 9" all round it is 300lb at the front and 250lb at the rear
