For starters basic round brush should do it to lay down basic shapes and gradients, after that you can apply texture brushes for for the texture of the surface.

At first I would only paint in grayskale/black and white and add a color layer afterwars, then you should learn about colour theory and paint directly with the colour selected instead of colorizeing a grayskale painting. You dont have to paint directly with the colour instead of a grayskale, but its a very handy skillset to have and a good way to understand colour better.

Most artists use a mix of grayskale and painting colour directly, first they lay down basic form in grayskale, then they colourize it with a colour layer and paint onward with direct colour.
