Aight, so SBA's random Rimworld advice:
When picking your colonists, try for a well rounded group (as much as possible). Priority skills are cooking, medicine, construction, and shooting/melee. Intellectual will be important too, but not right off the rip. Plants can also be clutch if you want to rely on farming rather than hunting for food.
Traits are a real barrel of gas. You could have a great roll on a colonist, only for them to have a deal breaker in their traits. Stuff like chemical interest/fascination, pyromaniac, slothful, neurotic, volatile I don't deal with at all. They'll have a bad day, have a breakdown, and start fights with other colonists and/or lighting shit on fire. Others like pessimist, abrasive, misogynist/misandrist are irritating to deal with, but more manageable.
Here's a full list and their effects:

Once you land, you'll want to build a small shelter and some beds. Once you get that sorted you'll want to figure out a food source.
Research batteries as soon as you can. Once you're making food you'll want to build a fridge to keep the meals frozen so they won't go bad, which means you'll need a air conditioner and enough electricity to keep it running 24/7. I typically try to keep the kitchen, fridge, and dining room all close together in order to cut down on travel time.
Turn on manual priorities, and order them like this-ish, obviously depending on what each colonist is good at.
I set up my base somewhat like this, depending on the seed and exactly how much space you have. I'd avoid using wood walls whenever possible, as they are very, VERY flammable. I'd recommend steel if possible, or ones built from stone cut from chunks at a stonecutter's table.
