Small speakers are just as good as large speakers except for the lower frequencies, you need a sub for that. Get speakers that fit the stock locations, just get high quality ones and for really good sound you will need a decent amp. Many ultra high end sound systems use smaller-ish speakers and they are always round. In either case use the stock speaker size.
The round design is for stiffness, as a stiffer cone will produce sound more accurately. A ovalized cone is more flexible, and can resonate and flex at certain frequencies, coloring the sound. A round cone is inherently stiffer, as the voice coil pushes/pulls the cone back and forth, the cone and surround are loaded evenly, meaning the entire cone shape does exactly what the voice coil is trying to do.

Yeah I've just learned this about the AU cars, that sucks. Well, not if you're ripping them all out anyways! The US does indeed come with the full 8 speaker set (dash tweeter, dash 3.5, door 6.5, and rear 4.

You don't necessarily need a 3.5 to go there, it could make for a lot of extra work. A good matched set of mid/tweet should be plenty, even for a loud, clean, high end setup. If you're using a group of three drivers, it gets a bit more complicated. That means either buy a processor to do all your crossover points and amp each driver individually, or buy a set of 3-way matched drivers that come with their own dedicated passive 3-way crossover unit (like the 2-way passive crossovers that come with most 2-way component sets).

Personally, I'm just doing a 6.5 in the door with some sound deadening, with the tweeter up top. I may do a recessed pod so the tweeter isn't buried, but we'll see what works best when I eventually get the car...
