How would I go about creating a link aggregation from a Cisco Cat4500-series switch to a PA-5020? I'm shooting for having multiple links between the two devices for redundancy (and load-balancing too, if possible).
What would I have to do on the Cisco side of the aggregated link? What about the PA-5020 side of the link?

You would configure the interfaces on the Cisco in an Cisco EtherChannel group.
Here is a great article on that:
http://www.ciscozine.com/2008/11/04/configuring-link-aggregation-with-etherchannel/
Next you would set up the corresponding interfaces on the Palo as a Aggregate Interface Group.
The details on how to do that can be found on page 98 & 99 of the PA-4.1_Administrators_Guide.pdf
Cisco best practice is to use an even number of interfaces... ei: 2 or 4 or 6 or 8 1000Mbps ports.
If you have SmartNet support on the Cat4500, Cisco TAC should be able to help you set it up no problem.
