Hero....

I would lead out, 250ish or so, maybe more. You probably want to get your chips into the pot, and if he doesn't have the flush too, he might not bet again if you check - giving him a free card would be a terrible result if he has a higher spade in his hand. (edit: and loses value too imo)

Yeah, leading 220-250ish is about right. There is little value in trapping.

So say I bet 250 and he minraises me again. Then.....

Push?

For me, having a flush against a better flush is like having Kings or Queens vs. Aces preflop. You don't mind losing a bunch of chips if it happens.

def. lead out. he prob has 2 pair and will raise you and you can go all in with your flush. I also dont hate a 3rd raise on the flop and looking to get all in with your ~13 outs and some FE!
