What you have will work, with a few improvements.

I'm a little confused about the sleeping bag...depending on the weather, you'll need something good to 20 degreees or so. I use a Sub-Kilo bag from REI, but they don't sell those any more. You should be able to find something like this pretty easily .

But it sounds like everything you have will work. It's basically good stuff. The tent is fine.

You'll want to be careful with the weather, because you may not want to be out in a full blizard with this equipment (or any other equipment, for that matter!) but this stuff will keep you basically dry and warm. And that's all you need.

You don't mention a stove or a pot--I think you will have to get those. And I don't take nalgene bottles, they weigh too much. 32 oz soda bottles work better. I'd leave the chair at home,

And I will be that you take way more clothes than you will need, which will make your pack heavier than it needs to be. But you'll learn.

In fact, I would suggest that the first thing you do is try all this stuff out. You don't have to go on a epic trip, or even a three day backpacking trip. Just take your car to a campground somewhere and try to live for a day or two with what you have in your pack.

What you'll find things that you don't need...and you can leave them at home next time.

BUt I think you are in good shape. All you need to do is use it!
