You say you don't require/want a sub, because of this i would be inclined to opt for components up front and 6x9s in the shelf, (or under it).....
The Alpines you linked to are meant for use in conjunction with a sub really, (hence the fairly high lower freq response of 70hz), also the sensitivity is a little low for such a small amp.....
The Infinity 'Kappa' you linked to are a better bet, unfortunately these can sound rather bright/harsh but will play much louder than the Alpines due to higher sensitivity and a lower impedance of 2ohm, obviously this will drag more performance from your Sony amp, but installation is more critical, (mids need a sealed deadened door to perform well & tweeter placement needs to be spot on to avoid or rather cut down on harshness).....
The Rainbows linked to previously are without doubt the best alternative so far, but again even these will require decent installation to get the best results......couple these with Rainbow 6x9s for a little low end and you should be almost there......
but, as previously stated, for best results you require a sub of some description, so whichever way you go its going to be compromised in some way....
