You're missing out on a lot of capability.
1) You first have to define what "optimizing the color image" means
in the context of producing a grayscale rendering. An optimized
rendering for color presentation is not necessarily the best way to
prep for producing a grayscale rendering.
2) Conversion from one color model to another incites losses. Every
time you convert to Lab or to Grayscale, you lose some data, some
resolution.
3) Layers and Adjustment layers are a very effective means of making
non-destructive, selective edits to images, and can be very finely
tuned. An image doesn't need to have anything "horribly wrong" with
it to get a huge advantage out of using layers to adjust and shape
its rendering, whether in RGB or monochrome.
The B&W conversion rendering methodology presented here is a good
simple way to do it, but leaves behind a lot of selective adjustment
possibility.

Unless there's something horribly wrong with an image I don't "use"
layers. In photoshop I convert to b&w by first optimizing the
color image as much as I can. Then I use this method.
1. Create a new adjustment layer "Hue/Saturation"
2a. Set Hue to -180
2b. Set Saturation to +100
2c. Set Lightness to -100
3. Change Mode to Lab Color, (if asked, yes do discard the layer).
4. In channels delete layer a.
5 Convert to gray scale.
Adjust curves or brightness/contrast for fine adjustments.
This is the easiest method I've found, (thank Cotty, for posting it
here a while ago). that gives very good results.

Help is appreciated

Hi Gang
Apologies for 2 pictures in one week.
This is a B&W conversion of a shot taken Oct 10, 2005 of the
abandoned Maynooth
Station.
Still needing more experience on this stuff.
You can see the remains of the old bed to the right.
Converted using Channel Mixer in Monochrome setting.
