"one blue MH and one white MH" will give your tank a weird apperance, one side being white while the other is blue. I would add 2x250w 65k lamps to your configuration giving you plenty of light for SPS, clams, etc.
I'm confused about those Jalli pc's you have. PC's have much more wattage than that, sounds like you have 4 NO flourescents. Full length VHO's for your tank are 110w (assuming you have a standard 4' 90) and for pc's 24" lamps are 55w-65w, never heard of 40w. Hmmmm....
