That is definately an Ensete ventricosum ''Maurelli''...I have two E. ventricosum myself and love them!
The leaf curling is to protect the leafs from sunburn as they were grown in less light that what they are getting now. The new leafs you will get from now on wont be doing that. As for the burnt leaf,i guess it grew that portion of the leaf while in transit and was too tender for the sun it receives. The rest of the leaf may survive but it will also be curling with sun.
The ICs indeed look quite stretched out! I am sure they will be fine though and in 2 weeks they will start looking good already!
Btw,i am very happy to see your Musa sikkimensis survived! Well done!!! Continue to watch your watering carefully and it will grow to be a beauty!
