Planning for 2010

I have to do a planning for my Sales Division for 2010. I need to perform this using my actuals June 2008 to May 2009 data and also need to load the planning data.

Whether the Actuals and planning data will be stored in the same fact table? If not what are all the respective tables for Actuals and Planning?

2) Once I load the Actuals and Planning, how do I project the trend for 2010?

Can the gurus can explain me the steps that I have to perform to achieve the above tasks?
