I can come at it from a slightly different perspective and give you some advice on what NOT to do after seeing them in Iceland last year.
I figured I'd google the best settings etc when we were there, then panicked when we saw them on the last night, couldn't get access to the internet and went with gut feel. I thought I was doing the right thing by going for a smaller aperture and longer exposure time. I don't really know why I thought this, but I did. So I ended up using something like f/14 and 25-30 second exposures for most shots.
Turns out I couldn't really have been more wrong. Though I will say, that they all looked great on the LCD on the back of the camera. So I didn't really experiment with wider apertures or shorter shutter speeds.
Things I read since getting back said to go for the shortest shutter speed you can get away with and let the ISO go as high as it needs to be. Certainly my 30 second exposures ended up with very little definition to the lights themselves and it meant any trees or bushes also ended up blurry with such a long exposure time. I'd take the advice above, shoot as wide as possible and go for 5-10 second exposures, and just let the ISO fall where it does.
Try and get some context. Buildings, trees etc, just something to show some scale. Building are better as they don't move (see above).
Use the widest lens you can get your hands on. I had a 24-70mm. Shot most of it at 24mm, but could have done with being wider.
Remember to look all around you. We were incredibly lucky that on the last night of our trip, they started and continued exactly in line with the house we were staying in.
But they started in one direction and moved above us, then all around. If you only direct your gaze and focus in one direction you might well miss something spectacular above your head or behind you.
Here's a link to some of my shots. I'm doing this to illustrate what happens when you get it wrong, not that I think they're any good. These were the best of the ones I could rescue.
Scroll down to see them. And see where I went wrong...
If I was going again, I'd use a wider lens, and go much wider on the aperture. So it could be shorter on the exposure time.
I think the most important thing however is to take heed of the advice above. Don't get so caught up with trying to capture them that you fail to experience them. It's an amazing spectacle with a genuinely 'magical' feeling.
ETA: From your current kit, your best bet would be the 10-18 lens. On a crop body such as the 1300D, it's broadly equivalent to 16-28mm on a FF.
Tripod is a must.
1300D is likely to be fairly noisy, so I'd open the aperture and zoom as wide as they go, set a shutter speed of 10s and set the ISO to auto. See what that gets you.
