Attached is a basic walk through of the omoplata (so you can see the angle change) and the rollout (which, from what it looks like, was actually as intentional sweep on my part, as I started grabbing the pantleg right from the start). I finish with a triangle, actually, so I attached that pic to answer the second question.
EDIT: Since this covers basic questions, I've folded it into the Back to Basics thread.
Ahh, Thanks. That helps alot.
Also; The pictures will definitely help me pull these off now.
