var string:String = "something 'is' \\fishy here";
trace(string);//something 'is' \fishy here
string = string.replace(/(['\\])/g, "\\$1");
trace(string);//something \'is\' \\fishy here

Answer 2

Amarghosh's answer is spot on. If you want an easy way to test out AS3 regex, Grant Skinner's Regexr is awesome.
