Jesus - you are supposed to have a thread each arent you??
Jim the Junior - I drift an S12 and they are great starter cars - cheap with lots of power. Can be an arse once you get proper good (100 mph+) as diffs and coilovers are difficult but a good starter. You can pick them up for anything from about £250 to £800 these days
Marslar - you cant
really drift an FWD car, so Id go for the RWD one. If you are just looking for on road control and stuff, then go for it, but if its pure drifting you are keen on look at one of the many school days on eurodrift and driftschool.
Crippledstoner - doesnt matter which way round the engine is.

Handbrakes are only really used for initiation, and usually only when you are fairly advanced. Concentrate on the throttle and the clutch more mate
WindyJake - 340's are supposedly alright, but Id try and stretch to a 1.7 - a 1.4 is going to struggle in the dry
Damo - all RWD cars would do it so everything you have mentioned is cool. Id advise a Nissan, but then just as many people would say a beemer.
And relax
