What photo painter software would you suggest?

I am a "Sunday Oil Painter" beyond a beginner stage. I would
like to work with transfering photos to my computer & then using oil painting computer technique to color.

What software program would you recommend & why?

How does a Wacom or similar box or tray apparatus fit into
this. Which one do you recommend?

I have Corel Painter X and I like it and find it easy to use. It is very effective.
