Looking at ordering 2 maybe 3 flashes off ebay YongNuo "YN-460 Speedlite" and was trtying to work out what I need to work these all at once from the Nikon D5000 I have. If possible provide links to certain other pieces of equipment I might/do need for this to work.
Also can these be mounted on a standard tripod or do I need another attachment......

All guidence is much appreciated.........
