The most common style, and one that I have used is K D D K with. The Left Kat being A, Left Don as S, Right Don as L, Right Kat being ;. Its important to find the most comfortable binds for yourself. As for tips I would suggest really listening in on the song and try to play on beat, but at the very beginning I assume you might be struggling with which note is which. In that case just play to get used to the game mode at first.
community/forums/topics/175867 This guide is also very useful. Teaches a lot of the basics and even has a pattern practice maps where you can see and play the different types of patterns you will encounter in a song. Make sure you put in practice of good habits. Try to really hit clean patterns. Make sure you rest as well. You only get better after you rest and take in everything you practiced.
As a side note there is single tapping, full alternation, and in between. Most people would recommend single tapping at the start. However if you can full alternate go for it as it is a skill that will come in handy far down the line.
