You are fortunate in having the tile roof! White paint, dark stain on the corbels, preferably new dark-framed windows....and yes the stone and the columns should go.

All I see is an over done mcmansion and I have no clue what a Santa Barbara look is. Post pics of what you want then maybe we can help. Okay so I looked at theis style and your house is going to need a lot of work I would not paint the stone I would have it removed or covered and if at all possible that whole thing at the front with the columns and jug and round window should be removed. This is one pic I found so maybe not quite what you are thinking,

BTW is this for you or a client ?

This is what I would like to achieved. And yes, I know there is a lot to do. I will paint the railing black abs change the windows to black frames. The wall color is the dilemma and what to do with that stone...paint or covering it? Plaster it? Is that possible?

Are you fixing up a client's house or is this your own house? The Santa Barbara colors are mostly off white. Plastering over the stone would look make-do, not like an expensive update.

Some option

I think I would go with white stones as well.

Definitely paint all of the metal black. If you keep the stone, use off-white/cream/light tan. Then pick a slightly darker color for the frame around the windows.
