What do you suggest? Also if I go with coilovers, I want to get the BR series. Will I "need" a camber kit (F+R) or will I be fine with just that set-up?

Coilovers are far better than lowering springs if your purpose is a trackable car. With coilovers you get dampers matched to the (typically stiffer) spring rate, and adjustability. The spring rate on the BR series should very street friendly, just turn down the shock setting at the end of the track day. Progressive spring is a little friendlier for the street but fixed rate is going to do a little better on track in most cases.
Whether you will need a camber kit is going to depend on how much you lower the car, even slammed the car doesn't seem to gain an absurd amount of camber due to the suspension design, but the more the better at the track. Look at Mike's car, he is lowered and still short on camber at the track (no front camber adjustment), just make sure you get an alignment after lowering to correct the toe-in as that will kill tires in no time.
