Here's a pack of 41 kicks and 45 snares I happened to have.

They're nice and heavy for the most part, good for dubstep ;]
That one drum sample is called an amen, since it's taken from a song called Amen Brother by The Winston Brothers. They're are lots of variations of it all over the internet, and I have some myself that I could share with you, except I'm not sure if you can work with .rx2 files in Pro Tools.
Oh by the way, do you have a drum-slicing tool in Pro Tools? That would open up more opportunities for samples I could share with you.
