do the soaps and the pumic stone also get rid of callous'?

Pumic stones will. If you want to toughen your feet, you should try to soften the callus rather remove it. There are quite a few foot creams that will do this. Also, soaking you feet in epsom salt and tea will help to both dry and toughen your soles. I've found that green tea works well. Black tea is cheaper and works better, but it may stain your skin temporarily.
