The G27 is a great wheel, but expensive. The Driving Force GT doesn't have the clutch pedal or full gear**** (only up/down and buttons on the wheel) but it costs about 1/3rd of the price so it depends on your budget. As for the games recommendations, it seems only TobyK read the OP since the others are recommending arcade-style and/or console games. The most realistic simulation game out there is probably GTR2, although it's a little old and I don't know how many people play that online. The F1 games are also pretty good and I think there's even a group of people from MyBB playing (or there used to be). Need for Speed: Shift 2 is also pretty good. Not as realistic or detailed as the others (similar level to Gran Turismo 5 actually), but it's pretty fun in its own way.
