Regarding the suspension - it can be fairly difficult to sort out by the seat of your pants. Especially if the front and the back were not designed to work with each other. There are some basic equations you can use to put yourself in the ballpark for spring rates, and if you know the unsprung weighs at each corner, and the car's weight, the shock companies can give you a setting that will be close. As a rule, the softer the set-up, the wider the window will be for acceptability. This is because softer set's have lower frequencies, in which the harmonics are more widely spread, so it's easier to find a quiet frequency with no harmonic problems. Harmonic will manifest themselves as is elations, boomy periods or vibrations which seem to come and go.
