Rename tables and Build Indexes Dynamically in SQL

I have a need for a stored procedure , where user can pass the tablename,schemaname and indexname as input variables.

Then the stored procedure should accept those as input variables and do the foll steps: The tblname, fieldname and indxes can change .

1. Rename existing tableA to tableA _PREV
2. Select top 0 * into tableA From tableA _PREV
3. Create clustered, unique Index on FieldA Such as CREATEuniqueCLUSTERED INDEX [IndexName]  

   ON dbo.TableA (FieldName);

   GO
