You may want bug spray; DEET works best but it will eat through plastics like camera gear or rain jacket membranes so I prefer to use physical barriers: black (easier to see through) no see um head net, or full jacket if you want. Cover rest of yourself with 2 layers if you want best protection against bugs.
Should probably bring sunscreen, chapstick with spf, sunglasses, and a wide brimmed hat. Skin cancer/sun burns aren't fun to deal with.
Maybe a rudimentary first aid kit if you want: Some tweezers, gauze, tape of some kind, band-aids. Benadryl, antacids, diarrhea meds etc. if you want some peace of mind.
A toque is always useful to have. Good for some extra warmth at night, sleeping, chilly mornings, etc.
Should probably bring a knife of some kind just for random tasks, whittling, carving a spatula for cooking, or food prep. A small folder will do but a full tang fixed blade is best for more rugged tasks. A small axe can replace a knife, if you wish.
Trekking poles help for long distance.
As for tents, I like my Eureka Midori 2, but I use it for solo to put my gear inside with me. It was like $150CAD and has held up great for I think 5 years now. Just gotta wash any dirt off after your trip and dry it out before storing.
Sleeping bags I prefer down because they pack small and weigh less for the warmth they provide. However, they are useless if they get wet and I guess I have a minor allergy to down so I always wake up with a stuffy nose. Worth it though.
Eating utensils, just bring a spoon from home and for anything you can't use a spoon, use your hands or shovel it into your mouth with the spoon. Can use your knife to carve some rudimentary chop sticks if you wish.
For cooking, depends on what you are making. Spoon can be used for most tasks desu.
Most people bring way too much stuff when they are starting out. If you're new at it, you'll learn over time what works and what doesn't. See what others use and adapt.
