Well.. I think yes and no. Your preflop play made sure that you've only got about pot behind on the turn so you've put yourself in a pretty shitty spot. There's nothing particularly wrong with the reraise pre, but I think you know that just calling pre is a more standard play 200bb deep that will keep you out of trouble. I like that as played you fired 2 barrels but I don't like that the second one was so small.

So to summarize, just call pre. I'd like your reraise more with AKo because AKs has so much value in multiway pots that there is no good reason to try and make people fold preflop. Let them put in dead money.

yes and no

pre and flop are fine but I don't like the turn. You're better off betting higher or just checking. ie. give up or increase your fold equity.
