Hi,
Here are tips I give to first-time players to help them play more competitively from the get-go.
For your first placement, try to find the spot that has the greatest number of wood and brick 'pips'. You need a lot of wood and brick to bootstrap your principality, and whatever else you need you can usually trade wood and brick for. Whatever else you get from this placement matters less (but ought to be *something*, not desert or open water).
To a lesser extent, you also want to determine which is the resource type that will be the most rare in this game (fewest total pips on the board), and you want to try to get in on that.
For your second placement, geographic location matters much more. Try not to get caught with a whole section of the island closed off to you. In general you should prefer to go far from your first settlement, not near. Next look for any resource type that you could be in danger of getting choked off from completely, and try to place your settlement where you can get access to this resource before the choking-off happens. Similarly you want to make sure you have some access to the ocean. You may also use your second placement to try to constrict your opponents' expansion plans. All other things being equal, you should just try to maximize your total pip count. Don't worry too much about having all five resource types accounted for in your initial two placements; you will be expanding soon. Also don't worry too much about which free cards you're going to get; they'll be gone soon.
Have goals. Always know what the next thing you want to build is. If that next thing is a road, know why you want to build that road -- to block a player from getting into your territory? So you can build a settlement at the end of it? If the latter, make sure you won't get beaten to that settlement spot, or you'll have wasted your road. In general, road wasteage is a bad thing; only occasionally will you get lucky enough to convert your wasteage into a longest-road victory.
For the most part it doesn't matter whether your settlements and cities are evenly distributed among hexes of all numbers or whether you have a disproportionate number of them on "9" hexes. The main problem with the latter is that you are more vulnerable to the robber.
Before you trade, ask yourself what they're going to use your resources for. Will they use it to hurt you? Build on the port you desperately needed, steal your longest road, block you in? If so, ask yourself if you really have any realistic hope of getting that port or longest road or freeing yourself from your current prison anyway. If not, go ahead and trade anyway. If another opponent is also offering to trade with your nemesis, go ahead and trade anyway if you can. There are no points deducted for sleeping with the enemy.
A 3:1 harbor is generally nice to have, but probably not worth going out of your way for in general.
If you are in danger of getting cut off from any one resource type completely, you must pursue a harbor strategy. This means both securing a 2:1 harbor and developing very high production of that resource type. Failing that a 3:1 harbor will have to do.
If a particular resource type is on the board great abundance (say, two 6s and an 8 are all on grain hexes), getting to the appropriate 2:1 harbor for that resource type becomes much more valuable.. even if you don't personally have an abundance of access to that resource yourself. (The player(s) who do will probably be trying to trade it to you.)
If you are weak on a particular resource type, and have no hope of getting more settlements on that type of terrain, you should prioritize upgrading those settlements you do have into cities. Of course, if the resource type you're weak in is ore or grain that puts you in a bit of a bind! See then the previous paragraph. This is somewhat less of a problem if there is another player strong in this resource but weak in a resource that you yourself are strong in.
File under duh: Avoid robbering the guy who's holding the development cards in his hand. Avoid playing a soldier when you're not the one currently robbered.
Try to remember who's been collecting the resources you want lately, so you know who to robber.
Don't get in a race with someone for the longest road or largest army unless you are pretty sure you can win it (or you are pretty sure that winning it is your only hope).
And finally:
Get the Catan Event Cards! This add-on makes resource production much less volatile, so it's more likely for the winner to be the player who truly played the most shrewdly. Which gives you better feedback on whether your own strategic choices are working or not.
