okay so I didn't real any posts other then yours because im a bit busy at the moment but going with a 10 Gal is fine. take all sponges out of your filtration as the sponge will build up phosphates, use carbon and GFO. now you said you will settle with fish only but you should get at least 5 lbs of live rock to help filter the water as well as a 240-425 gph powerhead. as far as lighting goes use something with a 10k rating or over to reduce the amounts of algae in your tank. oh live sand will also help play a huge roll in filtration. Good Luck
