One thing I have not decided on is powering the arduino. I have not gotten so far as to decide on or even figure out how to power it. A couple options would be to power it from the wall, by using a power 5v power supply and sticking it in a project box. Another option is some kind of battery, which woudlnt' make a whole lot of sense. The Third option is power it from USB and plug it into my computer. The only problem i have with that is it becomes dependant on having a USB power supply. I think I may opt for the power supply option, as i could fit one either in the project box or the outlet-in-a-box i have. Decisions, decisions!
