Thanks for the info Ken. That info really helps! I'm good... keeping busy tricking out my wife's SLK. For the price of a GIAC chip, I can do every single mod in the book available for the SLK.
Back to my original question before I was rudely interrupted by Ken. ;-) Does anyone know the redline RPMs in the forward gears?
No, the only reason why I was asking was that I got cut off a couple of times at a little past 6000 in first gear recently while the other gears were at the red mark on the tach. I never really look at the tach when I drive in the street and I only looked recently because I hit the rev limiter.

The reason you reach cut off (rev limiter) at ~6000 RPM in 1st gear (only a problem near or at WOT) is because the Tach is analog and the limiter is a direct digital read on the crank. In 1st geat at WOT the engine spins up so fast (due to the 13:1 overall ratio) that the analog Tach can't keep up with actual engine RPM. So when you reach ~6000 RPM on the Tach accelerating in 1st gear (~WOT), the engine is in fact already at red line. In the other gears, the acceleration rate of the engine is "slow" enough for the analog Tach reading to accurately relay actual engine RPM.
When accelerating at WOT in 1st gear, I initiate the 1-2 shift at 5800-6000 RPM...maximizes the power and provides much smoother shifts, since trying to shift smoothly once the limiter engages is just about imposible.
