I need this image in a grayscale
rgb(82, 82, 74), hex:
How can I do this on Fireworks or Photoshop?

You don't actually sound like you want greyscale. You want a toned image.
You can do the same exact thing by adding a Color Overlay Layer Style set to color.
To make the entire image grayscale:
First, understand that greyscale is a scale of bright-to-dark values that have nothing to do with color. Two very different colors can appear very similar or identical if you simply desaturate the image, because only the color, not the tonal ("grey") value, was providing the contrast.
Here is an example of a color image that clearly shows contrasting colors:
Watch what happens if we simple desaturate the image, apply a simple gradient map or change the layer's Blend Mode to Luminosity with a black, grey or white layer below:
Wait, what? Where did the rectangles go? Although we perceive the colors as different, they have exactly the same greyscale tonal value -- something of vital interest when you want to convert them to greyscale.
Photoshop's Black and White adjustment layer at its default setting does a slightly better job, but not much:
That's not a big improvement, but if we adjust the color sliders a little, we get a result that is a much better representation of how the original looks:
So you're best to use this approach, then add the one additional step that will give you the color value you want.
You now have your greyscale image based on that exact color, and only that color. How you can verify that is a matter for another day. It's not hard, but it takes a while to explain.
Simple answer: add a Hue/Saturation layer and turn down the saturation slider. Select colorize and adjust the hue to choose your color.
there are a multitude of ways to do what you're asking.
