can you easily access the vegin area with out reaching over your flowering plants?
can you completly seal off the veg + flower sections this "MUST" be lightproof
if your only useing cfls and floros you can cut down on the extraction a small fan or two will surfice
excessife extraction noise will 1, give your grow away 2, keep you up at night
i got a 20" box fan in the summer but it sounded like a chopper was landing on the roof
you can swap and change things throughout the grow but redesigning and rebuilding you grow space when full of plants will piss you right off
have a good think about what you will have to do in your room over the next 10-12 weeks
watering,training,pruning,trimming and tidying,pest control, takeing clones, ect.
make sure you keep thing under control
if mumsey sticks her head in a cupboard with a couple of small plants that are neat, tidy and well managed she wont be as shocked as she would finding a steaming stinking jungle speweing out of your wardrobe

work smarter not harder
