The REI Passage 2 tent is pretty good, just heavy. It's luxurious for one person with gear, and you won't get one much cheaper than what they're selling new ones for now.
I don't have any input on a traditional sleeping bag. If you decide to go with a quilt, I'd look at a Hammock Gear Econ Burrow. Good pricing, not outrageously heavy, and reviews indicate they're pretty true to temp. It's also still a down quilt, which I personally strongly prefer over synthetic insulation.
The Klymit pads are comfortable, and as pointed out above, can be had for a good price off their eBay site. I really liked the Insulated Static V I tried, especially for the price. But they don't work well with quilts. If you're willing to spend up to $200 on the pad, I'd get a new XLite or a used XTherm. The XTherm is a one-and-done pad, no need to upgrade later.
