Hi and welcome to the forum.
I was in the same position as you only 2 weeks ago and, as everyone has said, its very confusing out there. My setup up is very similar to what you are thinking of. I have a 4ft x 18" x 18", one halogen heat bulb down one end above a log & rock for basking, microclimate thermostat to control the temp, and the Arcadia T5 12% (which is amazing! see my thread http://www.reptileforums.co.uk/forum...l#post10952282
My viv came with wood chippings so I have stuck with it for now, but this is yet another area of conflicting views - some say sand, others say not!
Good luck with your venture into the world of BDs and I look forward to sharing some ideas.
