Thanks for the replies!
I do appreciate what you are saying in regards to just going out and learning how to use the camera first, my point is though that I'll only really have a solid income for the next 2-3 months before I head abroad so don't really have time to spend months learning exactly how to use the camera before I do leave, and hence want to buy the gear before hand while I can afford it.
Thanks for all the links, i'll have a read through them now.
