Don’t even think about a tent over 4# total.
I used a 4# Coleman Inyo, it was affordable (<$100) and served
me well. But last Xmas I got a Six Moon Designs Europa that
comes in ~2.5# . That and other weight savings reduced this
year’s pack by 8#. I could feel the difference immediately.
Tarptents are nice, but may not be for inexperienced campers.
They’re very open and must be properly pitched in poor weather
to be comfortable and dry. You’ll learn on the trail, of course,
but the beginning of a NOBO hike has the worst weather.
Don’t take a 5# pack or a 4# sleeping bag either.
(Pack should be <5# and bag <3#) My next pack will be <3#,
like a Vapor Trail or ULA-P2.
Weigh stuff. My 2.5# down bag actually weighs 3#, and my 3#
synthetic bag actually weighs 3.5#. I don’t know why.
My tent weight was really close to the advertised 4#.
Take the lightest gear that does the job. Make stuff do
double duty, where possible. If you want to try a tarp, use
your poncho sometime!
