Answer 1

My presumption is some of your quotes have been marked as won while others haven't...
You need to call WinQuoteRequest first before you convert it to a sales order. The order of events is this:
WinQuoteRequest
ConvertQuoteToSalesOrderRequest
This Returns the Sales Order in the repsonse.Entity (ConvertQuoteToSalesOrderResponse)
This is taken from this sample on MSDN
