Part of your problem is that you won't ever achieve better steering feel without giving something up in return. For instance, you can achieve optimal feel and directness of input by replacing your tie rod ends with spherical bearing rod ends (solid end links is what some people call them I think), but in return you feel EVERY bump, nook, cranny, and rock in the road.
Rack and pinion set ups are similar. While you're going to get a better steering feel, the amount of fab work and headache that goes along with it is sizable. Even with the crossmember kit mentioned earlier you'll run into problems, as it will limit you to front sump engine configurations.
