Michael:

Likley you don't have the Order Entry module so you may not find the OE*.CSV file in your sample data. If you do not need to print invoices from Adagio then you may only need to import the invoices into Receivables.

By the sounds of it you are doing a lot of things manually in spreadsheets. Often this is not the most efficient way to get transaction into any accounting database, unless the spreadsheets are exported from an external application and imported into the accounting applicable without further manual processing.

A good Adagio consultant should be able to help you sort all of this out. If you are not currently working with one please give me a call.
