Umm, Police Packages are pretty hard to find and they look sweet if you make them look mostly stock.
I like the mods you have in mind, but maybe the rims would look nicer if they were the same color as the rest of the car?
Also, I would leave the column shift alone and just put in a center console without the shifter. (Too much fabrication work, unless you are a sheet-metal worker by trade.) That is what I did recently, but I need to put some pictures up.
