Thanks guys.
I did use the BOM html file that Fritzing generates, but only to populate a more useful spreadsheet with fields for the purchase links and datasheets etc. Here are links to the schematic and the BOM. If you have a chance to take a quick look it would be much appreciated.
If you see any critical errors please point them out. Obviously I'd prefer to get it as right as possible before sending off for board fabrication and ordering parts.
Cheers
