The most common cause for starting problems is always the cables. Check not only where they hook to the battery (even up inside the cables, they can get all corroded!) but also where the ground hooks to the block.
If it's not making good contact, this will cause the problems you're describing - and a lot more. Even if it shows 12V, a lot of times, you may not be able to draw enough amps to start your car because of a bad connection. Fortunately, it's usually the main cables that have this problem, instead of the smaller wires. Also check your cable down to the starter.
If you're getting a weak 'click' when you turn the key, that's an indicator that at least things are hooked up properly. You're just not getting enough current for some reason.
