Update: I got it working. It ain't pretty, though.
Adding to my description in my previous post...
After deleting the active record, I wound up basically reloading the page. This page is passed a custom filter for the grid on the left, so I had to grab a couple items from the screen BEFORE deleting the active record, setting these items as Shared Results to pass to the page, and then 'reload' the page by showing the current Tab link again ensuring the view is filtered properly.
If the deleted active record is the last record for the customer, I detect that by querying the table and finding no results. In that case, I close the current Tab link and to go to another Tab link.
Here's a link to the screenshot of my actions - http://bit.ly/vOof2D
