I second Tara. She has a podcast you can subscribe to that has more meditations and talks than you could ask for, all free.
Her RAIN technique can be incorporated into urge surfing practice. Powerful stuff.
Dan Harris has a great app, though you have to pay for it which annoys me.
His book 10% Happier was a fun, easy, intro type read.
