Was going to say a light tent too, i have one made by hama which is fine for ebay sales and stuff. Triggers, well you can get £20 sets off Ebay although the Yongnuo RF602s (£35 ish) are brill if you can't afford or need Pocket Wizards. Don't forget you can also use a cable for your flash off camera (£30 at jessops), and your sb900 or D300 can work as a commander/slave. 5 in 1 reflectors are cheap too off ebay.
