THANKS!
Yup! You can do it. I'm looking to do the same thing soon, as the stock spindle on my Pista is bent.
The frame takes English cups. The spindle length depends on the cranks you plan to use, since you'll have to chage your ISIS cranks too . Just follow the crank manufacturer's recomendations in regard to spindle length.
What crank are you planning on upgrading to? Keep in mind that not all square tapers are not the same. Most cranks, such as Shimano use a JIS taper. However some cranks, such as Campagnollo and Sugino 75 track cranks, use an ISO taper. Although an ISO crank can be forced to "fit" a JIS bottom bracket, it will distort the interface and may fail. Just something to think about.
