For pasta that sticks less, I recommend putting the noodles in the warm water before it even boils. This washes off some of the starch.
You don't necessarily need to break the noodles in half if you'd prefer long noodles!
Finally, once the noodles are ready, you can put them through a strainer over the sink to get rid of water, then put them back on the stove at very low heat to keep them warm.
