Question Spring rate help Please!!!

Okay, I'm running out of things to work on before the snow melts (ya right it may never melt). I need to get the ride height settled, I need to know if I could do this with just springs or an I going to need to change out shocks as well.

Here is the corner data.

Front:

Wheel weight = 599 lbs.
Shock ext. = 17 in.
Shock comp.= 11.62 in.
Desired ride @ 14 in.
Inner pivot to Shock= 8.75 in.
Spring length = 12 in.
Control arm length = 11.75
Angle of Shock off vertical =30 deg.

Rear:

Wheel weight = 650 lbs.
Shock ext. = 18.75 in.
Shock comp.= 12.5 in.
Desired ride @ 16.25 in.
Inner pivot to Shock= 11.75 in.
Spring length = 14 in.
Control arm length = 16 in.
Angle of Shock off vertical =10 deg.

Okay, all you really smart guys help me out with this. What spring rates do I need, I'm so confused.

Well, it occurs to me that perhaps not all of the modifications I made are technically 'street legal'

Nothing good ever happened after this statement;
Hey Moe watch this!
