If you are just going to use a PC wheel as it is, a Logitech is the most hassle free.
Mainly because the profiler software allows you have settings automatically change on the fly when different emulators are launched.
The G27 is the current standard among PC racers. I don't care for the shifter, but the wheel and pedals are great for the money.
If you didn't want to spend that much, there are software workarounds to use the sequential shifter on the Driving Force GT as a 4 speed.
The pedals it comes with aren't near as nice though. Cheapest I've seen the G27 new is $204.
Other companies are making some sweet wheels, but they do not have profiler software than can change the settings or switch between combined/separate pedals on the fly.
If you want real arcade parts without FFB, the happ 270 degree wheel and pedals can be interfaced with an Ultimarc U-HID or old Logitech wheel hack.
I really like the spring loaded centering feedback on Ridge Racer control panels. It's so good that a lot of people remember the game having ffb when it did not.
I'm assuming that you're not going to get into real arcade controls with ffb, as that would be an extremely bulky and heavy thing to add to your CP.
Personally, I wouldn't sink much money into adding driving controls to a stand-up cab.
