What settings should I use on my Nikon D5100 for Taking Photos of Airplanes?

I'm going on holiday in a few days and I'm wondering what settings I can use to take pictures of planes, I don't think I will be using auto mode because it will be too blurry - I'm not sure though, I could be wrong(The planes that are moving).So If I were to use a different setting, what would I use (Aperture/Shutter priority - Or something Else), and also what particular setting is good for taking clear photos of planes whilst they are moving (Shutter speed).

I will also have two lenses with me - one is the standard nikon kit lens, the 18-55mm Nikkor and the other one is a 70-300mm Tamron lens, I will probably use the 70-300.Is that the right choice?

What would be a good flash for Nikon D3100?

I just got a Nikon D3100 and am looking for a decent flash that can also be used as a slave flash. Something that would work and be compatible with the RF-602. I'm looking for something that can do manual adjustments (not too worried about auto), but will also work ON my Nikon as an external flash attachment.

I'm looking at the YN-560 mark II flash.

Anyone have any suggestions and/or opinions about this or any other flash that is under $100 that has similar or better specs than the YN-560 mark II?
