Can't recall what it looks like, but the end that sticks out (and 'rubs' against the cam) should be rounded. Just make sure that when the decomp weights sling 'out', the little nub drops INTO the cam... it should protrude at rest.
I don't think the roll pin is required... my original had it, but my replacement didn't. To be honest, I have NO idea what it's for...I don't think it's to move oil around and lube the bearing surfaces of the camshaft, but maybe it's useful for something?
