For one thing, put on any equipment you find no matter how crappy it is. A leather armor and leather boots will protect you much better than bare flesh. Then of course, gradually replace them as you find better equipment.
Same thing with weapons. You might not like a particular weapon but even a weak one will help. OK, maybe not a balsa spear, but at least get a short sword or dagger or little axe or something. Trying to use fists against the blue carnivorous plants will result in death, I guarantee it.
