There is so much i could tell you. Do your research.
Like the mod said, buy dry rock... and seed it with some live rock......get dry sand not wet sand... that way you don't have any pest hitchhikers in the sand they died off... I prefer a deep sand bad (DSB) so 3-5" worth of sand on the bottom of the tank, allows copepods to develop quicker. as well as other organisms my dragonet eats.
you don't need a skimmer (i've had a tank running for 2 years now skimmerless) it improves clarity and helps in maintaining the water but, isn't necessary...
you do not need a UV steralizer...
if you are super concerned with keeping the coralline algae off of the glass, get a magnetic scrubber add that to your list.
Go FOWLR like you said, don't even try corals yet.. get some hardy fish and make sure you ABSOLUTELY cycle it correctly or you will have hella problems. Don't buy damsels to start, get chromis if your doing a fish cycle...if your going fishless read up on it, and make sure you do it correctly. If you get an anemone anytime soon i guarantee you it will die.
1.023-1.025 is the area of SG you need...if you can afford it.. a refractometer is much more reliable with a greater longevity..
You need lots of current, lots. you may think you have enough but if there are any dead spots your going to have an issue.
don't get discouraged, you will lose fish, and you will have outbreaks....don't get pissed off and tear it down...like they said it is an expensive hobby..don't cheap out either, it is always better to buy the better thing to have a cheap product that will break on you.
Also if your in cali, i would check the temp on the tank constantly without a heater, just to see where it stands...i've heard of problems with overheating...you want the temp to stay cooler than FW set ups, so a heater may or may not be necessary, you may need a chiller of some type if your lighting puts off too much heat.
If you have any other questions just ask, Kevin8888 normally gives some decent advice as well, he is pretty active on the salt portion of the forums as well.
