Sitting pad: Get a CCF pad and cut it to size if you're short. That gives you a sleeping pad and sitting pad. Light and packable sleeping bags are expensive. You'll have to do some research on this. The most suitable I've found on Amazon is the Kelty Cosmic Synthetic 0 for my uses, but it's not very packable or light. Naturehike makes decent tents. There are a lot of good sun hoodies out there. I would recommend just going by both the product and seller reviews. Socks: I prefer Smartwool over all other brands. I prefer the way they do their cushioning, and they fit me very, very well. I've also had better luck with them than Darn Tough. Darn Tough does have a lifetime warranty, but I feel weird about sending in used socks, hence I never utilized that warranty. Switching to Smartwool has been a godsend. Other items: Compass of quality, such as the Cammenga 3H or Suunto MC-2. Rite in the Rain. Pace count beads. Multi-tool. Sewing kit with good thread. Gear repair items, like Gear Aid patches or Aquaseal SR. A stash of snacks and electrolytes. Outdoor Research Ferrosi Hoodie.

A Kelty Cosmic 0° is around $200. It’s the often mentioned low cost down bag. It will cut your weight in half.

We already have Kelty Cosmic 0° bags from when we just car camped, but dang, they're huge and 5lbs!

Can you add more specific details? You have this labeled as 'travel' - but ask about camping gear. I assume you are asking about the 'wilderness' type of backpacking - right? What is the low temps you plan to sleep in? You say no snow - but 'colder temps' - a number would help. What is your budget? Do you have $500 to spend? $5000? You say 'wreck bank account - but everyone's bank account is different size. How old are you? Man or Woman? (many packs and sleeping bags are gendered) Do you already have a good sleeping pad? This is also critical to a good / warm night sleep. Do you already have a tent? Sure - Kelty is a find budget getting started brand. They make an okay Cosmic down sleeping bag that's popular for wilderness backpacking. I wouldn't go for their backpacks really.
