You can generate reports, but I don't think that will provide a neat or simple way to process current orders. 

The only way I can see to do it from within eBay is to go to the awaiting postage page, and click 'view order details' for each one (more specifically, right click and open in new tab, or just mouse-wheel click it, as that will automatically open in a new tab). Process the order using the order details, close, then move on to the next one. You'd have to do the accounting side separately (I personally calculate total revenue daily and use invoices or site reports to get my fee totals).
