Data conversion for New GL - Going live during fiscal year

Question

Hi Experts,
My client is going live on Oct 1 (fiscal year in Jan -Dec). So for data conversion we need to load P&L and BalanceSheet as of Sept 30, 2009.  I need your help to resolve few open issues. (we have activated Doc Splitting with Zero Balance and Segment )
1) When we load P&L balances - how can I assign Profit Centers to all these P&L iitems .  
2) What is the procedure (best practices) to assign Profit Centers to all the Balance Sheet items since we are going live during Fiscal Year
3) When we process open items  (AR, AP) in month of October how the Profit Center assignment will work?
(My client will be using Profit /Cost center terminology first time, so we need to map all the B&S and PnL items to Profit centers)
4) What is the best way to map all the Balance Sheet GL accounts to Profit Centers.
Sorry for asking too many questions. Any help would me very much appreciated.
Thanks,
Sam

Each P&L account balance has to be upload with cost centre, then automatically PC will be triggered.
2) What is the procedure (best practices) to assign Profit Centers to all the Balance Sheet items since we are going live during Fiscal Year
Let client decide the profit centre for balance sheet items, since they knows which balance relates to which pc
3) When we process open items (AR, AP) in month of October how the Profit Center assignment will work?
While uploading AR,AP balances, each line item to be uploaded with profit centre, automatically in october PC assignment will work.
(My client will be using Profit /Cost center terminology first time, so we need to map all the B&S and PnL items to Profit centers)
4) What is the best way to map all the Balance Sheet GL accounts to Profit Centers
