Does it make sense to buy 2 so both arms can be exercised simultaneously ?

Sure, working both arms simultaneously can make for a balanced workout.

Whats the resistance level or lbs on this?

There is no standard measure shown on the device. It is not a wide range of resistance, after a couple of weeks you can reach the hardest. It can average from 5 to 25 lbs

will this help with forearm splints?

The splints you get from doing heavy preacher curl, will not be helped by this. I never did find anything that actually helped with forearm splints.
