I've been trying to play flush draws more aggressively. Is this the right spot to be leading the flop? After I hit the 7 I'm betting again, otherwise I'd c/c... wrong?

I like your line of thinking. The allin player complicates things a bit.

A million % standard lead out here. There's literally no reason not to.

not really, because we do have an A, which means we beat lots of things he could have.
also, he's in for 1 sb, so that pot's tiny. we should build the side pot.
