The type of wheel has less to do with surface finish than the technique used when grinding the tool. Study the videos on YouTube (especially mine 
) to learn the basic geometry and then practice, practice, practice.
I generally keep a 60 and 80 grit aluminum oxide wheel on my grinder and take a few quick swipes on a stone to polish up the cutting edge.
In my opinion, the rests are a safety feature to keep tools and fingers from being pulled into the wheel, NOT to rest the tool on. Once you develop a good feel, it will be easy to lift the tool off the wheel to check your progress and then place it back on in the same position. That also saves a lot of time adjusting and readjusting the rests. Check out any of my grinding videos to see how I like to do it.
