Regarding your shock angle, SirSpeedy has it right. Your wide axle (nice!), combined with the Deuce Factory lower shock mounts, is giving you a lot of angle to the shocks. Don't go for the short shocks. They just don't have enough travel to give you a decent ride. The shorter lower shock mounts you're looking for are in stock at SAC Hot Rod, Orange CA (714-997-3433). Get the ride height you're happy with, and then change the upper shock mounts to put the shocks about in the center of their travel. This will allow the longer shocks to do their job more effectively.

You might want to stay with a "reversed eye" spring to keep the car nice and low. Most people prefer the reversed eye spring, and a new spring with pads between the leaves will ride much better, and will probably raise the car only a little bit, since your spring is getting tired.
