I am not an expert, at all, on lighting, but since no one has addressed some of it, I thought I would throw in my 2 cents worth. I personally necessarily do almost everything on the cheap so I am going to address this from my point of view.
Although your eyes will confirm it you just have to take it on faith that watt for watt t5 HO lighting is more powerful than PC and Metal Halide is more powerful than T5.
T5 3' bulbs are only 39 watts so you are probably going to need at least 4 of them over a 3 foot area. The nicer setups, with individual reflectors are going to have 5 or more bulbs, but for my pocketbook they are pricey. Actually what Tonya had/has is a pretty good setup. If you can find them used that's 2 clipon or hangin pendants at around $150 each and a 4 tube 3" @ $150-$200. You might be able to cut that all the way down to a 4 bulb 24", but now is only 96 watts and still is going to be $100 up. I heard you talking with Robert. If you can go with a partial canopy or suspended lights it may take a while to find but you can probably find ballasts, reflectors and bulbs for 150-250W MH at about $100-$150 per set (used), ideally using 3 sets. I think even 150s may be adequate for your needs but the 250's easier to find. Electronic ballasts are more, fancy reflectors are more and maybe not needed if you are not going to do SPS. The problem is almost everyone starts off not going to do SPS and eventually does. There are many other combinations and permutations but that's a quick picture. HTH
