now, for the glass i m releasing my own material library in which all the materials I have made are stored, U can get glass, mirror & water from it, it will even render fine with the default scaline renderar, but if U want try with mental ray too, simply apply it

as for the lights, first tell me with respect to the above screenshot, where is the window going to be, then apply a m area target light outside the window, so that light comes in your room from outside the window, increse the intensity to 1.5 & make it white light, then apply another target at the place of tubelight & also if U R going to show the tubelight, make it, & put the light2 behind it, make the tube light transparent & white material based,
Enable shadows & caustics in mental ray, decrese the photon entry & volume to 100 from 100000, and render, move the lights till U get the result U want
