Cloning database using data pump

Hi

we need to clone our database using data pump
Ours database is 10.2.0.4
Here is what we intend to do

1. Take an export of the source database with full=y
2. Install 10.2.0.4 on target database
3. Create a blank database
4. Import the source database dump file into target database

Is there anything else we should be doing between these steps?
Do we need to pre-create the table spaces on the target database before running the import?

Thanks
