Initiaz, Always use the sleeping bag rather than your blanket as the weather in the bush can change very quickly and I would rather be hot in a bag than freezing my nads off wrapped in a blanket. You can always unzip the bag. For a weekend jaunt you should only need one gas canister. As already said, toss the cans.
For myself I very rarely use a tent but always carry a good fly instead. Keep at it
