Is there a best for fan orientation on a radiator? Well, I'm not sure if it's the best, but I would prefer the front fan blowing in, and the fans at the back and top blowing out. Just so it's not blowing hot air out into the vicinity of my face or feet.

Pull (#1 picture) will probably work better for cooling your other components and not quite as well for the radiator.
Push (#2 picture) will probably work better for cooling the radiator and not quite so well for the other components.
No chance of installing a push+pull setup with 4 fans total?

My general rule of thumb is that fans mounted on the case (including radiators) go:
Front to Back, Bottom to Top.
That keeps the air flow in the case going all in the same general direction. It may throw heat into your case from the radiator, but it'll get pulled back out someplace assuming you have enough fans in there, and overall I think the better airflow in general outweighs trying to optimize for any particular component (with the one exception that if that particular component is the limiting factor in some overclocking build, but that's a corner case and my rule above is just a generalization).
The optimal case for any radiator would be cool air going in (so set up as intake fans). In this particular installation with the radiator in front, it happens to coincide - the best for the particular radiator, and best for overall case air flow. But if you''ve got a particular hot video card or problems with your motherboard sinks sitting directly behind that radiator, then you may want to take a closer look at it.
Some people like to "positive pressure" their cases to help keep dust and such out, which would be more intake fans than exhaust fans. I don't know that I've seen it make a lot of difference, but I won't discount it either since I haven't done a lot of testing with it.

Have your front fans as intake. The overall increased airflow will offset the slightly higher temperature air.

Both pictures are push actually...
I would go with Option 2 as well, have the fans as intake. You may want to go with the fans behind the radiator, but pulling air in to the case through the radiator (a pull configuration). This generally works better with lower speed fans. Whereas high speed fans tend to perform better in a push configuration.

When the 120mm AIO CPU coolers first came out, they usually came configured as pull/exhaust, intended to replace the exhaust fan at the top rear of your case. Testing showed that flipping the fan around to be be an intake (and push also) dropped the CPU temps via the fresh outside air, without really increasing case temps noticeably. Note that most enthusiast cases have exhaust fans on top right there too, so any heat coming in through the AIO is basically going to be getting sucked out right away. My own testing confirmed this. I also stuck an AIO on my GPU, and have that mounted as an intake/push in the middle front (not quite permanently mounted yet, but that's where it'll be located).
Like others have said, I'd go with option 2. The CPU will get more cooling, at the cost of minimally increasing the temp of your case and other components. As long as you have good airflow so the heat can get up and out, you should be good.
