BPC 10 Capex and Depreciation Planning in BPC

HI Gurus

I am building a prototype for Capex and depreciation planning and wondering if some one can guide me with best practices for this and help me understanding following:

1. If I am doing the CAPEX planning on Asset class level, do organizations generally go upto the asset level and if yes, how does the input schedules look like. and how this is integrated with P&L and cash flows.
2. How the depreciation is calculated (and how the selection for depreciation method is given) and how the accumulated depreciation is taken into account for Planning.
3. How the model in BPC is built to integrate the depreciation with Balance sheet and P&L.
4. How the actual data is taken into the ECC/BI (I mean, which standard data sources etc are used).
5. There are some starters kit available, how do we make use of them in BPC 10 (I have read that generally one has to do many changes to that to be usable on projects, so I just want to have a reference point from that).

Any ideas and suggestion for more understanding on this and any examples from BPC 10 NW would be great.
