RE: My future bow
Oneshot - You should listen to "longrifle" if you are trying to pinch pennies. I had leaches on my bow last year and they didn't make it more than a couple of months. I have switched to $1 worth of cat whiskers and my bow is quieter and they last practically forever.
The rest of your setup will do just fine. You don't need a $700 bow to go kill some deer! The Cobra Venom is a fine basic pin sight that will serve you well. Everybody seems to think you have to have wrapped fiber sights these days, but the Venom still has fiber optic pins so it will work fine. The Sidewinder is typically in the $70 range, but they have a couple of different models that vary in price.
I don't know anything about the arrows you asked about. I still shoot aluminum and they tend to be cheaper, yet with tighter tolerances, than most carbons. It's really a personal choice.
Good luck ... Shockwave
