It's early Stages in a $10+1 mtt on ignition, Blinds are 30-60, No reads on any of the players besides the guy in the SB who played previous hand aggressive with rags.

Hero: 3,710, UTG+2: 4,900, Cutoff: 2,348

Preflop:
5 players limp to me in the SB with 6s 6d I just call

Flop:
7c 4d 5h checks around to cutoff who bets 360 , I flat making the pot 1,080, it folds around to utg+2 who then re-raises to 900 making the pot 1,980
Cutoff proceeds to shove all in pot is now 3,908, With my open ended straight draw I hesitate and then call followed by UTG+2

UTG+2 shows 7h 6h, Cutoff shows 10h 8h

Turn: 10c

River
Qh

Cutoff scoops the pot

Should I have re-raised preflop? (I felt like set-mining without bloating the pot was the best way to go especially so early in the mtt)

Should I be calling the All-In? (Considering everyone in the pot did limp pre, I knew I was bound to run into some 2 pairs maybe a set at worse a, I was getting around 35% to call (correct me if I'm wrong) with my set)
