How can we preselect baby's traits, like, intelligence, memory, disease resistance, phsique etc. ?

As human genome project has successfully deciphered the genes encoding several traits, now the expectations are brewing up to exploit several important traits prior to birth, viz. disease resistance, color and stature, IQ level and so on. Would you please torch on this topic how far we are successful, and our hopes may materialized upto what extent. Thank you.
