Answer: Many plants suffered in the extreme spring season this year. Although the foliage may be damaged, I would still expect the plants to be alive. Established plants will recover and look good faster than replacements will be able to fill in, so you might want to give these a chance. You can check to see if they are alive. Live wood will be supple with green just inside the bark, while dead wood is brittle and discolored dull gray or brown. Trim off any truly dead wood, and gently strip off the damaged foliage. With a little time, these should leaf out, regrow and look as good as new. As far as replacements, nearly everything suffered in that untimely and unusual frost and every flowering shrub I can think of would have suffered. But, you could try hollies, for example.
