My first inclination about this job is to abandon it... no, I didn't say rewrite it... I do mean "abandon it". This will change the Fill Factor on all tables and that's an absolute Bozo-no-no. There are (should be) a large number of static definition tables that never/rarely change that should have a fill factor of 100 just for performance reasons. Also, any table that has a Primary Key on an IDENTITY column should also have a Fill Factor of 100 on that Primary Key because there's no chance for interceding rows, so no interference on INSERTs/UPDATEs by the 100 fill factor but will increase the speed of SELECT's and decrease the storage requirements on the IDENTITY Primary Key... clustered or not.

The basis of the code is a really bad idea...
