I suggest researching the care and housing of ball pythons first before buying morphs. Though albinos are coming down in price, pieds are still a few thousand (unless their prices have really changed in the last year or so).
As both morphs are recessive, you will need to breed the offspring together to get both morphs showing in the offspring. NERD has great articles on genetics and how recessive traits work and double recessive odds.
If your goal is to have albino-pied snakes in the first generation of breeding, then you will need to look for either double het for albino and piebald, or piebald het albino or albino het piebald. Finding these may be tricky. The kingsnake classifieds will be good place to start looking, also breeder sites like NERD, Ralph Davies, etc. (see forum sponsor banners).
IN the end you will still be looking at 3-6 years before producing albino/pieds snakes. If you buy pied and albino babies, you have to grow them up for 2-3 years to get them to size/age for breeding. Then take the double het offspring and breed them to eachother, need to grow them up for 2-3 years again.
Pied albinos have been produced before and do look interesting.
