My database server is using 100% of the processing all of a sudden and it doesn’t seem like I have any more traffic on my sites. What can I do to look where the increased traffic is coming from inside of SQL Server Management Studio?

A typical cause of high processor usage is unoptimized queries, from stored procedures or otherwise. I would take a look at what stored procedures you have running frequently and make sure that they are running efficiently and are properly indexed.
