[Res] Capture a Response from Groovy script to be used later

I am working on a Groovy Script that uses OAUTH for authentication to hit a web-service posting a json payload and then returns a response as a string. I am wondering how to capture the individual attributes for use later in the test. Either in a property or as a value that can be compared to a JDBC query run later to validate that the payload was loaded as we expect.
Steps
1) Groovy Script calls HttpUtils() groovy script added to SOAP UI /bin/scripts/ to handle oauth calls
2) This httpUtils() script takes the oauth Attributes and makes the postData call to the web-service returns a string of results posted
3) Use the results posted or the string returned later in the test case as attributes to verify data in the database is as expected

Script...

//imports
import com.eviware.soapui.impl.wsdl.teststeps.RestTestRequestStep;
import com.eviware.soapui.support.XmlHolder;
import net.sf.*;
import net.sf.json.*;
import net.sf.json.groovy.*;
import groovy.json.JsonBuilder;
import groovy.json.JsonOutput;
import groovy.*;
import groovy.lang.GroovyObjectSupport
import com.eviware.soapui.report.JUnitReport

//Define Json Builder
def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context)
def builder = new JsonGroovyBuilder()
def slurper = new JsonSlurper();

//Define json Payload for request
builder.json(){
body = "{JSON Payload}"
}
//Content Type
def contentType = "application/json"
//accept variable for return object
def accept = "application/json"

//Make call to web-service using httpUtils() for oauth
def g = HttpUtils()
response = g.postData(URL,body,contentType,accept,consumerKey,consumerSecret,tokenKey,tokenSecret)

//debug logging variables
log.info("response=" + response);
campaignResult = groovyUtils.context.expand(response);
log.info("campaignResult: " + campaignResult);


Script log.info of course this comes back with out the \n
Wed Aug 22 08:07:09 EDT 2012:INFO:request={"result":{
"id":1000,
"sfId":"23412351243",

"creativeUrl":"",
"links":[{"rel":"parentcampaign","href":"http://localhost:8080/campaign","method":"GET"},
{"rel":"salesplan","href":"http://localhost:8080/campaign","method":"GET"}]}}

So I can see the result from the log.info("response=" + response); and log.info("campaignResult: " + campaignResult); but can not get these values transfered to another step. I have tried using slurper and parser but im not sure if that is the right way to go when attempting to use this data later for verification.

Any help would be appreciated.
