Without seeing the extent of the rust, that question can't be answered. Basically, if you can poke a screwdriver through the rusted section, that's a really bad problem. If the rust is just on the surface, use a rust converting polymer blend, such as Rust- to stop the rust and convert it to a paintable solid surface.
Yes, if the accumulator is leaking refrigerant, replacing it should fix the leak. As long as it is done properly.
