Mouseover healing

Hello,
I can't seem to find addon section in the forums and since i rolled priest i decided to post here.
What are the best addons for mouseover healing in vanilla?
I downloaded Grid and Classic Mouseover.Disabled X-perl(just in case,because it's buggy anyway) /Blizzard Self Cast and tried the following example macro with mouse on my own player frame(Not in party if it made any difference,which i doubt)
/cmcast Lesser Heal (Rank 1)
It had no effect whatsoever.
If you can tell what am i doing wrong or mention some better alternative for mouseover healing+addons it would be appreciated.Please?
