This warrants a standard brake system inspection at a repair shop. Typically, you'll see the smoke from just one wheel, almost always on the front. Be sure to mention the locking brake / smoke / hard to accelerate, because the common causes of that don't show themselves with normal inspection procedures. We need to know the extra things to look for.
One of the more common causes of a dragging brake is a constricted rubber flex hose. They often have some type of mounting bracket in the middle of that hose. Rust can develop inside the bracket where it is wrapped around the hose. On older Chrysler models that crimp can be bent open a little to solve the trapped brake fluid. On most import models the hose has to be replaced.
One of the most serious causes of locking brakes is brake fluid contaminated with a petroleum product such as engine oil, transmission fluid, power steering fluid, and axle grease. This gets to be a very expensive problem. I can share the details if it becomes necessary. One clue here is it affects both front wheels at the same time.
If you let me know what they find with the inspection, I can offer more information or advice. Most shops give you a written estimate. That way you can compare estimates from multiple shops and know they're both expecting to do the same things.
