As I am often off-trail (sometimes purposely
;) ) I have not had much success with the 'ultralite' packs due to their dearth of durability over time.
But to further muddy your decision-making waters, you might look at the Granite Gear 'Vapor Ki'. A woman-specific pack that comes in short. GG's customer service is exemplary.
At 2# (for the 'short'), I don't know if it qualifies as 'ultralite', but 2# is pretty
light and it IS bomber and has gobs of padding on the hip and shoulder belts.

I have used the men's version (Vapor Trail) to carry 10 days of food & gear, so it can hold up to a pretty good load, too.
Another option may be the Osprey 'Atmos 50'. It's now discontinued and replaced, I think, with the 'Exos' series, but there is one (short) on the Phoenix craigslist for $60.00 right now. Saving almost $100 would go pretty far in helping to fund that Western Mountaineering down bag you always wanted.......
Cook kit..... You do not mention what types of meals you cook, but if you merely heat water and pour into a bag, any pot will do - maybe even consider an alcohol stove. If you sometimes need to 'simmer', however, alcohol stoves are at a disadvantage and canister stoves fare much better. A lower, wider pot is more efficient with your fuel than a narrower, taller one. REI (as well as Snow Peak, MSR & others) makes some decent titanium
pots, but when figuring cost-benefit, titanium is difficult to justify. IMUSA (available in the pots/pans section @ Target) makes a ‘grease pot’ that is as good as most backpacking-specific pots and is about $5.00 (vs. $20/$30 for aluminum or $50 or more for titanium 'BACKPACKING' pots)
Another option is the ‘Stanco’ Grease Pot available through Amazon ($9.99) or Bene Casa pot also from Amazon. All of these pots are aluminum.
If you need a small bowl, try the lid from a CountryTime lemonade canister; it fits down inside the grease pot.
A very good insulated mug is REI’s Aladdin mug ($ 4.25) you can also find these Aladdin mugs at thrift shops sometimes for about a buck.
You didn't mention a mattress as an item you need but Campmor has the Pacific Outdoor 'X-Lite Thermo' pad for about $50. It's much more durable than a Big Agnes Insulated Air Core at the same weight. It is insulated, 20" x 72" and 3" thick! It is NOT ultralite at 24oz., but, man, are they comfy. Rolls to about the size of a 32oz. Nalgene.
