Sparty, I think you'll find that if you take some measurements inside of your canopy and compare them to the overall measurements of 60" fixtures I believe you'll find that they most likely won't fit inside of your canopy.
A 48" fixture is all you need. With 2 metal halides and some suplemental T5's. Before I made the decision to build a LED fixture for my tank I was going to get a 48" fixture and my tank has essentially the same dimensions as your...just a little shorter is all. A 48" will give you all the spread you need so a 60" really isn't going to give you much more benefit. I don't think you'll find any fixtures with 3 metal halides under 60 or 72 inches.
Metal Halides come in different Temperatures/Kelvin ratings. The lower the kelvin rating is then the more its going to replicate real sunlight. Lower kelvin gives you better growth and higher gives you better color. Many people like to go somewhere in the middle with 12,000k or 14,000k bulbs to try and get the best of both worlds.
