I need to know if this config is good to play most games GTA IV mainly at high settings with decent rates, and I know "GTA IV is a bad port" la-de-da, so don't bother mentioning that, just straight up answers!
Will it be a good overclocker GPU/CPU wise?
Can I use my 2.1ch speakers in a 5.1ch sound card?

No overclocking on the CPU if you don't get the "K" CPU's. The HD4890 is still a good card so upgrading to a I5 2500K would be a priority for overclock.
Yes you can use your speakers on the 5.1 card but if you do not have the card already just use the onboard digital.
The HD4890 is loud, hot, and power hungry, but it is on the same tier as the HD5770. Unless it's an old card you already have, get a HD6850 or 1GB GTX460 instead, or if you can afford it, a GTX560Ti.
Unless you're going for quiet, you don't need an aftermarket CPU cooler for a non-K Sandy Bridge, because they don't overclock. The included stock cooler will suffice.
