@Consumes only applies to the request message body so it isn't applicable to GET since that doesn't allow one. Example 1 looks right to me, to extract the JSON you would replace the "MyRequest myRequest" parameter in the action method with "@QueryParam("myRequest") SomeType myRequest".
SomeType can be any type that has a String constructor or a static valueOf or fromString method that takes a single String argument. See the javadoc for @QueryParam for full details.
