My opinion is that it's best to learn how to write the kana and not just how to read them. It's actually quicker (I think) and if you can write them, you can read them, so learning to read takes no additional time at all. On top of that, when you know how to write the characters, you don't get confused by the similar-looking ones (for example, ね, れ and わ or め and ぬ) because you know how thye're put together.
The method that worked for me was the
Kantan Kana video series. Get a pen and paper, start the video and copy everything the presenter does. Spend a few minutes practising after you've watched the video, then do the next one. I did the whole series over a weekend, and I'm not in any way specially gifted or talented at this kind of thing.
