For boots, you need to try them on. I personally prefer mountaineering boots to hunting boots. For me, La Sportiva, if the fit your foot, Scarpa also makes great boots.
Pack can be similar to boots. If you are technically inclined, Seek Outside is a great option that can be used for many things. Exo also makes a great pack, they should be releasing the K4 soon, so if you wait a few months you can probably get a deal on the K3. Stone Glacier and Kifaru also have great reputations.
Those are the two items I would not skimp on.
For sleeping pad, the Neoair Xtherm, but you could get away with a foam pad and a cheaper inflatable on top of it. I'm a huge fan of down sleeping bags, but for one hunt on a budget they would be low on my list. That said, sleep system, cook set, and shelter ate areas where a lot of weight can be saved. When I decided to start cutting weight I was able to loose several pounds in those three areas. If not expecting very cold weather, just get a canister stove like the Soto Winemaster and pair it with an appropriately sized Toaks pot.
