Luke,
Dave has identified the main thing you need to do, and at a club you should find someone who will give you the opportunity to try some of their tools and see what you prefer.
Something you don't say is what you want to make. If it's only bowls, then most of the spindle tools will be a waste for money, at least to begin with. But you will grow into them slowly.
Another idea is to find a (reasonably) local shop that does woodturning tools and equipment. Axminster Tools is slowly opening shops around the country. The Toolpost does just about everything, if you live anywhere near Oxford. Both Axminster and The Toolpost have excellent websites. Your profile does not say where you are, but if you can give us an area we should be able to point you at somewhere as there are many others.
Lastly the toolmakers all have websites, so look up, Henry Taylor, Hamlet, Crown, Ashley Isles & Robert Sorby for tools.
