Right Steps for Maintenance plan?

Hi,

I want to create a maintenance plan in which it has :

1. Changing recovery models (SIMPLE and then back to FULL)

2. Reorganizing Indexes

3. Shrinking the database

4. Taking a FULL, DIFFERENTIAL & LOG backups.

So, is this my correct order?? If not then what should be my correct order of the numbers??

Please advice....
