Bars

Yeah I tend to get a bit obsessed when I get into things and I'm like a sponge wanting more and more information. Sadly with cycling and many other things I keep expecting my online banking page to greet me with a white flag

Most people use road drops for general purpose track riding, which is what you'll be starting with. So there's no need to feel that you have to use bars that are marketed as "track" bars.
As you progress you will decide if you prefer a sprint orientated bar and perhaps adapt to a lower riding position.
