I love those sliders in the color picker and I totally forgot to mention them. LOL I use the Brightness and Saturation ones alot.
Hmm... I'm not sure why the other tool wouldn't open up. You could try opening it through the menus
Enhance> Adjust Color> Adjust Hue/Saturation. I'm not sure what limitations the trial version may or may not have.
And if you want to do EVERYTHING.. you'll be creating your own brushes soon.
