is night rating even regarded in the training in the states for helicopters?
Yes you train at night, but there is no such thing as a night rating---it is simply not required because you are allowed to fly at night as long as you meet recency of experience requirements.
another thing I've been told by calling helicopter schools is that once you got your commercial license its best to get a turbine rating in like a jetranger which boosts your chances of getting a job
Nope. They just want your money. There are companies out there that will train you in a turbine aircraft when you have the enough hours to meet their requirements.
there is a shortage of helicopter pilots
This is a joke right? There are lots of helicopter pilots. There IS however a shortage of helicopter pilots with "certain skill sets". Here in the US, it is getting more difficult to find quality utility pilots. But as Whirls pointed out----unless you are qualified to work here, you will not get a utility job here.
