Hi paulmfinn, and welcome to the forum :-D
Personally, i recommend you to go for the MCSA 2012 certification path. It's pretty similar to SQL Server 2008 and your knowledge will be more updated.SQL Server technology is changing very fast. Microsoft top certifications will be retired this year.. we have to be prepared, who knows what's next...
Good luck on your exams !
