I have been backpacking most o my life, and would like to offer a little advice. First, you dont need a stuffsack for everything. My advice would be to put everything into a large garbage back, including your sleeping bag, and roll it up tight. This keeps everything nice & dry. Then, add the tent, in the bag it came with, sans poles, on top of that. Closed up, you should still be fine. Top pocket (if there is one) put a FAK, headlamp, TP, and snacks. The trick to packing is to put what you wont use on the bottom. Food bag at the bottom of the pack, not in your garbage bag though. Then, the garbage bag with your sleeping bag, change of clothes, jacket for warmth, hat, gloves, extra pair of socks, and wet weather gear (unless its needed or wet). roll that up tight, put it in the pack, on top of your food. Next in goes the tent, without the poles, on top of the garbage bag. Lastly, your wet weather gear, if rain is expected, or if it is wet. Me, I ALWAYS pack this on top of everything else, because the jacket is an effective windbreaker.
Outside, strap your sleeping pad & tent poles to your pack. Thats it!
