Well, a wheel and pedals give you more accurate control, more precise control. At first you would probably suck even more than with a normal controller but you might caught on faster afterward since it's more "lifelike" to use a wheel anyways.
Either way, with practice you should beat your own times you made with a controller.
Any mild-mannered RWD car on S1 tires will give you a good feel for refining your throttle and steering inputs. The RX-7 or BMW 135 would be good places to start, and yeah, Suzuka has pretty much every type of corner covered.
Maybe move onto the M3 after that, and the Z06/Ford GT when you want the challenge to begin.
P.S. GT5TT had mandatory traction control when playing with a controller, but it was turned off when playing with a wheel. That could have made up a lot of the difference if you're somewhat heavy-footed with the wheel. I'd recommend no driving aids whatsoever in GT5P.
If it becomes a chore or you lose interest, don't feel bad about turning them back on... after all, it's about having fun.
"Last question; how much of a relief is it that Gran Turismo 5 is finally coming out?
(Laughs) Couldn't be happier! Especially because Kazunori Yamauchi took a lot of time tweaking the game as he always does but the fact that he took the time to make sure the game is 3D compatible is great. He put a lot of effort into it and it obviously shows! If you haven't played it yet, you should it looks absolutely fantastic! "
You seem to be talking about a system rather then say per track, and the problems that 3d could create on tracks being built as we speak (hopefully).
Even to make it compatible with 3d technology that Sony hadn't released till this year? 3d TVs were only released last month. The public corporate push for 3d only really started January this year.
Although I guess there's nothing to really suggest that they couldn't have been working on 3d and reasonbly perfected it three years ago for any system.
ps. I wonder what problems for games 3d really presents. bugs wise.

I'm not sure if I should say this, for if they would fix this the game would be delayed another year, but:
What annoys me in every game that has cars in it, is that when a car is driving really slowly, and the driver turns the car around entirely, he just keeps both hands on the steering wheel and turns it about 120 degrees. In real life, one has to turn the wheel maybe to 300 degrees to get the wheels to the end of their range.
The only game ever to get this right is, strangely enough, Grand Theft Auto IV. When driving quickly, Niko barely has to steer, when driving slowly, he turns the wheel around while letting go and grabbing on again.
I read they've taken this out because from cockpit view you notice the animation can't keep up with the wheel under all circumstances, no idea if that's true.
Could also be problem with hands clipping through hands that only looks bad in cockpit view, but hopefully they could fix that with alternative animations.
Whatever the reason, it's been dropped since they added cockpit view, it was there in GT:HD too.
