If you're playing relatively casually the curios you use might depend a lot on your playstyle. I'd recommend researching the quality formulas for the crafted curios, and the perception*exploration/survival needed for the foragable items listed below. Try to focus on mainly these curiosities, though obviously if you've space in your study, put whatever in. If you become all rich and stuff others would become more effective, but start with these ;w;
Super early game:
http://ringofbrodgar.com/wiki/Cone_Cow - actually really good LP/hour end game, but not worth the effort
http://ringofbrodgar.com/wiki/Barkboat - Always super good but like the cone cow, just to a
much lesser extent
http://ringofbrodgar.com/wiki/Wishbone - Good filler curio from Q10 chickens in the early game, decent curio once you've highQ chickens
http://ringofbrodgar.com/wiki/Ant_Hill - all ants are good early game
http://ringofbrodgar.com/wiki/Emerald_Dragonfly - the entire reason you should settle by a swamp initially

I'd recommend making 4 characters:
A forager/hunter:Generally one would make 3 of these. One with their hearthfire in a mountain, one in a swamp and one for general use like hunting/looking for resource nodes. They would have enough exploration*perception to effectively forage their respective zones, and survival high enough to not softcap the foragables. Constitution is optional if you want to swim on it for some reason. Agility should be high enough to teleport between their Hearthfires(which would be in the biome they're foraging) and village Idol.
A farmer: Simple enough, pump as much LP as you can into farming and maybe get a little bit of constitution so you can plough/harvest for longer before drinking/sitting in a chair. Make sure to go full nature. This character should never everererer leave your walls. ever. don't do it.
A crafter: This is the more annoying of the characters to make, but in my opinion the most needed as it will be keeping all of your curios/food high quality.
Stats a crafter needs includes: Strength, intellect, perception, psyche, dexterity, cooking, smiting, sewing, survival, carpentry, and marksman. You can delegate some of these stats to other characters, but I'd recommend concentrating them on one most of the time. Look at all of the crafted curio formulas/LP per hour before deciding how you want to build yours. This character should never everererer leave your walls. ever. don't do it.
Lastly a miner: Just strength/constitution - make sure to go full industry/barbarism
Your early game goals:
1. Build a Brick/Crossroad/Village Idol wall at least 3-5 ender's screens away from a river. Only worry about things required to achieve this goal first off. Remember to keep your keys offline on an alternate character.
2. Building a craftsman/farmer. The above should make this one obvious, keep in mind building a forager first might mean better curios/food for your craftsman/farmer, do whatever works best for you. Don't be afraid to trade ! You'll always do better if you understand the market and what's valuable. If you pick an industry and trade for everything else, it's possible to live entirely off of it.
3. If your craftsman/farmer are set up and you've a brick wall you're doing pretty well. I'd recommend researching stuff life armor class, how much damage ranger bows can do, ramming mechanics, raiding tactics as to better defend yourself.
