Overall length for stock shock towers is usually about 64.5mm. With the lowerered towers, I like 63.5 to 64.0mm. I know it may seem like a very small difference, but it does change how the car drives. I think it's important to measure your shocks . The car will generally feel a little more "stuck" with a slightly shorter shock. You can also tune the balance of the car slightly as well. Sometimes I run 63.5 in the front, and 64.0-64.5mm in the rear to get the rear end to rotate a little more.

I personally use Tamiya steering knuckles right now. I honestly don't see the chatter as a terrible thing. I usually try not to turn the wheel that much anyway. Something to think about is how differently the car reacts when it is unload (up in the air on a car stand) in comparison to how it is loaded (while on the ground driving). It usually won't chatter NEARLY as much on the track.

The FF suspension blocks control the amount of arm sweep in the front end. Arm sweep changes a few things in the geometry like ackerman, wheelbase, and inboard toe all at the same time. I've found the more arm sweep you run, the more steering the car will have right at the apex of the corner. Less arm sweep generally gives more steering into the corner, but less going through the middle and exit.

Hope that helps!

Here is the picture I am talking about from the Reedy Race 2011;
