Regardless of what you decide, do yourself a favor and make sure you can reach everything. Nothing should be more than 30 inches away. Don't climb on your layout. It's hard on the back and knees. The "ideal" layout would be one where you could simply walk up to everything and nothing would be more than 30 inches away. Understanding that this isn't a perfect world and the "ideal" layout is difficult to achieve come as close as you can.
Lastly, get some rubber tile squares over your concrete floors. Those are a killer to stand on for any length of time. :-)
