Take a long breath and have a go using what you have at present. After a while other necessary accessories will come up but just buy them as you need them. Buying a heap of accessories is a common mistake people make when they first start out as most of the bits just end up in the bottom of their kit not used eg. my complete kit of colour filters!!
When you have the need for something just post a question here and we will happily help you spend your money
