To answer your question -
1. Trial expires after 30 days.
2. Updates can be applied using RUM. please download RUM from - http://labs.adobe.com/downloads/aameetools.html
its documentation is available here - http://labsdownload.adobe.com/pub/labs/aameetools/aameetools_rum_docs.pdf
If you want roll out image where you have deployed Master collection, then install a trial package on one machine, creates its image and roll out image to other machines. Then run AdobeSerialization executable on all machines to serialize it.

Thanks for the information.
Will RUM still run successfully on the Adobe CS6 Suite on my master image when the trial period has expired?
RUM will run irrespective of license/no license on machine, but all the available updates might not be applied. Reason - there are different category of updates, some of which need valid license to be present on machine. So only those updates which dont need valid license will be applied - in trial expired scenario. Ideally valid license should be present on machine while updates are being deployed.
