Alexandra,
I see you are looking for high-quality and lightweight items, but you do not have a lot of money.
Backcountry.com lets you sort multiple brands by price. Moosejaw is similar, but I do not like their customer service.
Some brands that offer items on the lower end of the price spectrum:
Fleece:
Mountain Hardwear
Columbia
Synthetic Jacket:
Mountain Hardwear
Stoic
Marmot
Sleeping Bag:
EMS (Synthetic, Solstice 20 is perfect for you)
Mountain Hardwear (Synthetic)
If you would like a down bag, you will get more durability and warmth for the weight. It will cost you. Western Mountaineering is the way to go. Read about care on their website, it is important. I still suggest a synthetic like the Solstice 20.
Tent:
The Fly Creek will be plenty durable for your trip if you care for it carefully. I suggest getting a different tent since you are 6'1". Perhaps a Big Agnes Copper Spur?
Tent Brands:
Big Agnes
Tarptent
Marmot (cheaper)
I HIGHLY SUGGEST using Outdoor Gear Lab at outdoorgearlab.com to check on how different brands measure against eachother.
Thanks for joining our forum :)
P.S. as a taller woman, you will almost certainly find that LONG sleeping bags and men's jackets will fit you better and keep you warmer. Ignore "women's" labeling for outdoor gear and wear what fits your body type best. At 6'1", this will be men's clothing, most likely.
