What is your budget like? Are you willing to drill your tank? IMO dont cheap out on anything, you will end up regreting it in the end. Get a large skimmer, and good lighting, if you are like most people in this hobby you will end up wanting "bigger and better". I would suggest 3 x 250W metal halide and T5 supplimental lighting and somthing of a mid grade skimmer or better (bubble king is nice but big $$$). Drilled is the way to go if you have the capability to do so, glass cutting bits are fairly inexpensive on the internet. The more water volume you can add to your system the better, so get the biggest sump you can.
Here is a little chart that might help you in picking a skimmer
