I would go with the octopus skimmer. I have one right now, the bh-100, and i think its an amazing skimmer. Right out of the box i had no problems with it and its doing exactly what its supposed to be doing. Very durable and trust me, the skimmer is high grade quality. Also, the one your thinking of getting will have no problems skimming your tank amazingly. Its rated for up to 135G so ya it will work. As for the lighting, i would go with T5 lighting, but if you have the money to splurge, go with metal halide lights. If going with the T5, lookup the "Current USA: Nova Extreme Pro." With that light you will be able to have just about any corals you like.
