This is what Im going to do so far. Then maybe you can give me some advice.

My room will be 8x8x7. I only am starting with 24 plants. I thought that 2 600 watt HPS. would be good. Please correct me if Im wrong. I would like a really good ventilation system. I think thats my biggest proublem. Im not to familiar with the types of fans. I do want carbon filters or even a ozone generator. I also plan on having oscalating fans(wall mounted) If I should have more then 2 please let me know. Please help build my grow room.
