Not nearly enough people are watching this forum.
But let me see if I can help.
You'll need to take at least 3 steps:
1. Set up ContactService as a Web Service in the Database Integration Wizard.
2. Create a custom block in your application script that concatenates the two parameters you want into a single variable and then adds that variable as an intrinsic to the contact.
3. In the Multimedia admin tool, configure your agent screen pop to use the variable you created in #2.
For #1, use this document as your reference:

You're going to need to add the ContactService. On our system, the ContactService WSDL is located at http://[HOSTNAME]:9070/SOAOI/scripting/services/ContactService?WSDL
