I would replace the jetboil--there are a lot lighter ways to boil water (including the newer Jetboils).
Bag seems heavy for the conditions, and maybe for its temp rating (Not sure--I suspect most of us here are more familiar with using lower temp limits to compare bags than comfort limits). You can always supplement your bag by wearing your warm clothing to bed (which you are carrying anyway.
If you're serious about cutting weight, you might hold off on the backpack purchase until you've cut everything else. You may not need the volume or suspension (or pack weight) as your base weight drops.
The weight of a lot of your little stuff can be cut in half. Forget aerosol cans, for example (and deodorant). Seems like a lot of wet wipes, and will you really need a full roll of TP for 3 days? Pretty soon, 14 grams or so shaved off every item will make a half kilo or more.
Giving the total weight of all your packed gear, minus consumables (your base weight) makes it easy to compare with other gear lists.
What size canister is the jetboil fuel? A full 110 gram (net fuel weight) Snow Peak canister weighs ~200 grams. That would easily get me through 3 days, with plenty left over.
Your food weight seems high, esp. since 3 days hiking is usually only 2.5 days food (no breakfast first day, or dinner last day). Do you usually have food left over? If not, you may want to push your calorie density higher. I shoot for >125 Cal/28 grams (~4.5 Cal/gram) average calorie density, and am perfectly happy with around 600 grams/day for short trips.
