New Tank?

Hello,
I curently have a 37 gallon glass tank. In it is a Royal gramma, Zebra moray eel, Tube worm & a purple condi anemone. There is about 30lbs of crushed coral in there and 10lbs of rock. The coral and the rock were not bought "live" whatever that entails, but they both grow lots of green alge strands.
I am thinking of upgrading to a 75-90 or so tank. I was told that a underground filter would be best because of the sensitivity to metal in salt water fish tanks. So what is the best kind of filter to use? I have heard of these overflow and was wondering if they are worth the trouble and what they actually do.
Also with all that room in the tank when I do "Go Large" what other critters should I put in there.
Lastly can I just scoop all the cc out of the old tank, put it in the new one, drain the water over add the fish and then add new water? Or is it better to cycle the whole tank over then introduce the cc, rocks ect. to the new tank?
Thanks to all who reply,
Tom

I wouldn't use an undergravel filter has it will become a nitrate factory. Are you going to go fish only or reef? I suggest using aragonite or a sand bed as a substrate. Have at least 3" and it will help break down the nitrate. If you are going to with crush corals, using some in your tank now will help it cycle faster. If you are looking for a filter, get a cannister or simply have enough liverocks and sand.
