OK, not too shabby.

One problem with bic lighters is the buttons can get pressed when inside the pack and they go empty on you. They might need to be in a hard container like your cook kit or in your odds and ends box. Some people wedge then so they can not be compressed.

Now throw your sleeping bag and mat into it, add 10 or 15 pounds for food, make sure you have your fuel for the stove weight added as well.
(Food and fuel can just be weights for this test instead of the real thing. you only need to match weight and bulk.)
Put your maps, pencils and note book in.

Then put it all in your backpack and walk it about 5 miles.
(an easy a 2 hr walk on pavement, try to include an uphill and downhill section)

After you have got hold of a scale and done the walk with it come back and ask us about where to lighten it up.

You should only carry about 1/4 of your body weight.
You don't appear to be over that yet, but the rest of the kit might get you pretty close to it.
We can also talk about what stuff goes into pockets or onto the belt instead of into the pack.

It really is a good start.
