135lbs at 6ft?!?!?!?! I'm 6ft and weigh 200! does that make me fat? :O
aaanyways pretty much the previous post. for bindings, it's safe to go with name brands, try to find sales(burton sale on The-House right now) or used stuff because it'll save you a lot on you first setup. Goggles don't need to be anything fancy you can find them easy peasy for under fifty and they will more than do the job. Helmets ehhhh I can' tell you much about because I've used the same one I bought on sale for two years now.
