IMO, unless the 1 can of isobutane is feared near empty, you don't need 2 for an overnight.
Clothes will come with time...lighter is better but don't bring too little that you freeze to death.
How much rope, how heavy?
As for the slippers, if you go on 3 trips and don't use the stuff, stop bringing it unless it's part of your medical kit/survival pack.
A lightweight 800 down sleeping bag will serve you well if you find you like backpacking, it will be your most expensive purchase.
Depending on your tent and pack, that could be an easy way to shave off some pounds.
The miscellaneous stuff adds up, treat them the same as your slippers situation.

1 gallon of water
Pocket Rocket stove and small cooking set
2 cans of Isobutane
Clothes (this is where I could really lighten up. I have no lightweight clothing)
Slippers (I dont know why. I just thought it would be nice to wear some comfortable shoes after 10 miles of hiking. I didn't even use them)
Miscellanious(spelling?) items such as map, flashlights, lighters, and some emergency survival gear.
I think that was about it. My buddy carried the tent because his bag had a lot more room in it. I only used half of 1 can of fuel so I can take one out next time and I could probably buy a smaller can. I need to buy some lighter weight clothes. I am going to leave the slippers out next time. I packed a little to much food and I did not use all my water but that is something I would want to over pack. I did not think I packed to much stuff but my bag was full and seemed to weigh quite a bit.
