I have the following questions regarding installing Exchange 2013 SP1.  I currently have 2008 Domain Controllers and an Exchange 2007 Server.  Can I install Exchange 2013 in a 2008 Active Directory environment, and can Exchange 2007 and Exchange 2013 SP1 Co-Exist?

Yes to both.  That being said there are some issues with URL's that you will have to update.  For that I would look at : http://silbers.net/blog/2014/01/22/exchange-20072013-coexistence-urls/

As long as you are not trying to install Exchange 2013 onto a Domain Controller directly you will be fine.

yes, 2007 and higher can co-exist

SP1 is the same as CU4 which is no longer support so recommend using CU8 which is the latest and can do a new install directly from that build
