In this song @ 0:48 it goes really distorted and heavy. I'm planning on getting the guitar he used, but how can I achieve this distortion. What pedals do I need?

And another question, how do you make notes sustain longer. Even when I crank up my amp, and play some notes higher on the neck they only ring out for a second or two. Yet I hear all these bands playing these solos and having the notes ring out to really achieve a certain sound, but how can I do that?

It doesn't matter what guitar you use as long as it has good sustain, and he's just on overdrive with a slight boost to his mid frequencies.

The OD tone sounded really basic to me.

Just get a good amp with an overdrive feature. Distortion pedals are only necessary if you want to switch between different effects.
