I have also recently installed photoshop elements the trial version, I'll look a bit and see about it...

I'm using photoshop elements, because I'm used to it.
I am always working in greyscale but separate the RGB shades in layers, so they are easy to see.
I am giving the map a base layer with only two RGB values on it. One for the water and one for basic land colouring. On different layers I add the other features woods road and rail can go on one layer and still be easily seen but other land types need to be separated out to be easy to work with.
