It might affect temps a little, but nothing to worry about unless you paint a really thick layer.

A good spray paint should be fine.

If $$ isn't a huge concern you might consider shipping them off to get powder coated. If you just want to paint it up, and get it in any non latex based spraypaint should work. Automobile spraypaint is probably your best bet, should be available at any auto shop whether they sell body work stuff or not. I wouldn't spraypaint a CPU cooler, or GU cooler or anything like that as you'll get a nasty temp jump. If you're just spray painting the mosfet/vrm and chipset heatsink you should be fine.

So just unscrew the heatsink and spray them?
Do i need to sand them before?
By "automobile paint" you mean body paint or some special one?

Unscrew them from the back, and twist them till the thermal interface material lets go. Don't pull, I ruined my old graphics card by doing that, thankfully it was just a radeon 4*** series crap kicker that came with a RtR comp.

Yeah I mean body paint. I wouldn't bother sanding them, but you could. Chipsets don't really create much heat, the problem is without a mechanism of removing the heat they just keep heating up until they reach Thermal breakdown threshold, or reach a failsafe thermal threshold. Most chipsinks aren't even designed to be a cooler, they're designed to be a heat spreader. Take the Crosshair V chipsink, it's just a metal plate mounted to the chipset, no fins, no heatpipes, just a big metal chunk that spreads the heat out away from the chipset. So if you're worried about aesthetics go ahead and sand before painting, if you're worried about thermal issues I wouldn't bother painting.
