whats your budget?
for a low budget...
I would buy some decent shocks first (shorter stroke) and cut your springs making sure they are still captive with the shocks (i.e. 1 to 1.5 coils no more) see how you like that. Then go for some poly bushes for the lca and caster rods. Then some decent tyres and a good alignment.
there is nothing wrong with cutting a small amount of springs as long as they are kept captive.
