I am new to this as well and you look in better shape than me, but my first thoughts are:
Tent: There are lighter tent options out there, but a lot of this is preference. Zpacks Hexamid Twin would save you 22 ounces.
Rain Jacket: Heavy. I can't hike in any rain jacket, so mine is mainly for standing still or if it gets really cold. I have jacket from LukesUltraLite that is silnylon and weighs ~4.5oz. Lots of other options out there. Helium, DriDucks, etc.
Wind Jacket: Adds weight, but is great for adding a bit of warmth over a tee while hiking, light rain protection, keeping bugs off, etc. Houdini is one, but again lots of options out there.
