Enterprise.

1. Transparent Data Encryption

Transparent Data Encryption (TDE) is the primary SQL Server encryption option. It was first available in SQL Server 2008, and as with the SQL Server 2012 release, it's available only in the SQL Server Enterprise edition, not in the Business Intelligence, Standard, or Express editions.

So my next concern is licensing it.  I have a dual quad core processor server.  If I assign only one processor to the vm that will have SQL Enterprise installed, how many licenses do I need to purchase?

I would contact your reseller and have their MS licensing expert give you the best solution.  MS licensing takes 4 MBA's and a PHD to barely understand it.

If it is 2008R2, you can licence it on a server basis. For the 2012 onwards, if you don't have  Sofrware Assurance, you need to licence each core. In your case, even though you are using only one core, you need to buy 4 core licences (that's the minimum for the fist 1 to 4 cores) ..

Ouuuch!  Are there any 3rd party tools that will allow encryption on Standard Edition?

There are couple of options
1. Use Bitlocker drive encryption or similar products
2. Use database encryption keys at database/instance level  
An example of how this can be done is shown here
