Folks have covered most everything. In case I missed it, make sure you DIP EVERYTHING! Regardless of who you get it from, how big or small. Many folks have AEFW's and don't even know it yet. To avoid that PITA, make sure you dip everything and blast it with a turkey baster in the dip (thoroughly) before you put it in your display. Ideally, everyone would have a quarantine tank to make sure the acro is pest free before putting it into the display. While that it is not a luxury we all have, you can go a long way in ensuring the health and quality of your SPS by dipping them. It may take more time, but it just takes two (or one pregnant female) and you will be infested before you ever realize it. Dipping will help ensure other pests (redbugs, etc) don't get in the tank as well. RB's don't always die in a dip but those are treatable.
ORA corals (as mentioned above) are great ways to start out. I would make sure you can grow easy types of SPS before you ever try the wild colonies. The wild ones are some of the most beautiful but also the most difficult to keep. If you follow the instructions that others mentioned above (and read the stickies at the top of this forum), you will be good to go.
And yes, 8-10dkh is ideal but many will tell you they keep SPS dominated tanks that look amazing at 11-12 too. If you are (or plan on) dosing vodka to run a ULNS, you will want to drop your alk down to 8-9. If not, you should be fine where you are (unless you really want to bring it down).
