I had TCS on +1 50:50 and BB+1 for the longest time to get a feel for how the car reacts (then removed TCS for my 'real' laps). I personally don't want to disturb the car too much because the RPMs drop too much causing loss of acceleration. I find its better to keep her under complete control at all times and what Roamer said about just lifting (gas) is so true; understeer city.
When you brake, brake firm and when you release the brake, release faster than normal. I find hard braking really sits the car down to get her ready for the turn. While releasing it fast helps induce some oversteer that helps steer the car where you want it to go.
I shift a little before the redline, unless I'm going uphill, then I rev it out to the top. Here's a poor attempt at a walk thru:
T1 - Starting the lap try and hug the inside wall, I typically tap the brake as the lap begins. Turn 2, brake a little early and point the car at the fence on the left at the top of the hill and stay left as you exit. Turn 3, turn in late lift 5% to keep her from going to far wide on exit, ride the right 'wall' the closer you are to it the faster your T1 will be. Turn 4, brake (hard) after the dip, shift into 2nd for a split second to get more turn in, quick shift into 3rd while pointing to the white barrels on the inside.
T2A - Floor it through the slight left turn 5, straighten the car completely and brake once the car settles. Ride close the inside bush for turn 6 while getting the car 90 degrees (its okay to feel a little slow through here). Go into 2nd, let it coast up the small hill and floor it the moment the car touches the ground, quick shift into 3rd staying on the inside as much as you can. Enter turn 7 wide to the right and pump and release the brake at the top of the hill while turning inward. I also shift into 2nd because the landing isn't always consistent for me. Quick shift into 3rd for turn 8 and the only time you can get away with lifting and turning (because of the body roll momentum) is for turn 9. Don't let the car swing out wide, its okay to go a little slow and keep the driving line straight, hugging the fence on the right.
T2B - As you exit turn 9, straighten the car and brake softly to point the car about -45 degrees as you go enter the jump while starting to countersteer as you go over the jump. Aim for the right 'wall' and straighten her out going up the hill and get ready to turn in the moment you reach the top of the hill. Now the trickiest part of the lap, after you complete the fast bumpy downhill section (flat out), as you reach the dip, brake hard into turn 10 and the moment your car hits the dip and point toward the inside 'wall'. Again going slow here is fine as you want to straighten the car out toward the white barrel on the left as you go over that last bump. You should be able to exit this safely and flat out when done right.
T3 - The lumberyard is tricky and where laps are won and lost. Entering turn 11, brake stiff, release fast and shift down to 3rd and try and ride that inside wall on the right again. I tend to brake around the same time the T2 indicator pops up, maybe a little sooner if I'm really flying. For turn 12 I find I really need to minimize the incoming oversteer, which is harder than normal because its got a late apex so you can't enter the turn too early. It takes some finesse and timing to get the feel of that turn, again going a little slow to learn how the car reacts is great. There is a steep ledge through here, and destroys your lap. As for the final turn, I drop it into 3rd, brake early and wait until you are at speed before turning in, 52mph seems to be the magic number for me. Just balance the car out on exit, keep her on the inside pointing to the right wall and floor it out, no holds barred shifting late into 4th.
HTH and hope that made sense
