Stud H/L 3 to a low straight flush, with cards dead

[Wish]

Don't play much stud, but I do occasionally play in a micro-limit HORSE or HOSE tournament to broaden my horizons and blow off some steam. This hand is from one of those. First Stud H/L round, single-table tournament. Did I play this right? I'll only through 5th street, you'll see by then that everybody is pretty well committed to the hand, and results don't matter as much to me as figuring out how to play this game.

I have the bring-in with the 3 in the door, and 3 to a straight-flush and low. I made a full bet and called a raise. Despite seeing three of my hearts on the board, is this right? The raiser is the only other player who could have as many as 3 to a low at this point.

Another heart is dead, but I picked up a 4-card OESD, and 4 to a nut low. This feels like a strong hand, but should I be worried about the heavy action I'm getting here (considering I don't have a made hand yet), or happy for it?

I've got a made 75 low, but Seat 3 might have the same or better. Also picked up a 4th heart, and still have an OESD. But now the guy with KQ is coming alive and betting agressively instead of just calling. This street pretty much commits me to the hand, so the rest of it probably doesn't matter much. I'll post it later if requested.
