Here's the advice I can offer (also, pretty sure you can find everything you're looking for by searching the drift forums, and by reading the stickies there as well).
For starters, everything I write is in reference to using CH tires, manual transmission, and all aids off. ABS is optional.
Car:
Any FR car will work, but I think you'll find the best results if you start with a lightweight, lower powered car. My personal favorites are the Mazda FC3S RX7 and the Nissan PS13 Silvia K's Dia. Both can be drifted stock, but I would suggest tuning both to about 1100kg-ish with under 300hp. After a few hours of practice, you can try bumping up the power a bit, but I would suggest staying under 400.
If your looking for tunes for either of those two, a guy by the name of TwinTurboCH posted very good base tunes for both. Neither of these tunes are the most aggressive, but they result in a very smooth and predictable car. They are designed for the wheel, but also work well with the controller (aggressive DS3 tunes tend to be more "snappy" than wheel tunes...which makes wheel tunes slightly more forgiving for beginners)

Tracks:
Right out of the gate, I would start with the double hairpin at Road Course Indy. It's nice and slow (2nd gear, 3rd on exit for most tunes). Start by driving the section back and forth (not drifting) to learn the grip levels of the CH tire (it will probably feel incredibly slow). With each successive run, start using the throttle to induce controlled oversteer. When you feel ready to start initiating before the corner, the hand break is an easy way to start the drift. Also start using a slight weight transfer to help initiate. The goal with this section is to be able to smoothly link the two corners.
Next, I would go to the S-curve at High Speed Ring. It's pretty much the same as Indy, but much bigger. It's a good place to practice holding a consistent line and angle through a long corner. I'm usually in 4th gear for the first corner, quickly down to 3rd for the transition, the back to 4th, and then 5th through the exit.
Once you're comfortable with those two sections, I would suggest the first section of Autumn Ring Mini Reverse (done in both directions). A good place to get the hang of multiple corners of varying speeds. To switch things up, you can try the last section of A-Ring Reverse, but the banking of the final 180' corner can be tricky for beginners (gotta learn eventually though).
My last suggestion for a learner spot is the S-curves at Suzuka, done in both directions. On the downhill, don't worry about going huge on the entry, or trying to follow the D1 line. To start, just focus on smoothly linking all 5 corners.
Remember, the key is throttle control! Hope this helps
