For your pedals just pull off your rubber pads and put on skateboard grip tape. They'll be fine. you'll even be able to heel/toe reasonably well as long as your feet aren't too narrow.
For the intake it's fine to buy the cheap tube and add a K&N or Amsoil filter.
Accents (or other fwd cars) can drift. Whether a car can drift or not has more to do with the balance of the car and your suspension settings than whether it's fwd, rwd, or awd. You just have to treat it differently. I can drift my Accent without ever touching the e-brake. Professional drifters use braking and weight transfer to get the car sliding more than the go pedal, although the process for keeping a fwd car drifting is different than a rwd.
In this picture from last weekend I came from the left around a sweeping corner:
It's not perfect but in this pic I have swung the rear around the cones. I get more sideways than this too slightly after this pic:
Most people who drift don't use fwd cars and the best drift cars are rwd, but that doesn't mean you can't drift a fwd.
