Poor fuel efficiency and oil useage is dependant on driving habits. Yes, if you drive the car hard, gas mileage will go down and oil useage will go up (rotaries actually use oil to lubricate the engine seals). I think that's common sense, and if you didn't know rotaries used oil, I guess you should read about the car you're buying. Some people were reporting low gas mileage during normal driving, but I believe that was fixed with an ECU upgrade (could be wrong, it was a while ago I heard that).
I haven't heard of anything specific regarding gaskets, cold starts, or fuel pump issues. I doubt any of them, depending on which gasket, were related to whether or not the engine was 'mechanically sound'.
The RX-8 was in Car and Driver's 10 Best Cars for both 2004 and 2005. Not sure about the Consumer Reports review, but I never put much weight in that magazine. Problem is most people read that magazine about products they know nothing about. Read about a product you do know about in that magazine, and you'll see just how ignorant they can be.
I'm not saying the RX-8 will be as reliable as a Honda/Acura on average, but I definitely wouldn't consider it an unreliable car. Unless you're a straight-laced Honda guy who will buy a car for gas mileage and reliability over performance and character every time, I wouldn't cross the RX-8 off your list.
