Tibetan Buddhism, seeking info.

I decided that I want to get back into Buddhism. I had an interest in Buddhism when I was in High School but really didn't get into it because meditation is difficult. Over time I tried Christianity but left because it didn't suit me.

I decided to go with Tibetan Buddhism because it combines Hinayana, Mahayana, and Vajrayana schools of thought. As of now I'm getting back into Vipasanna (insight) meditation.

I seem to be having trouble finding good info online. Does anyone know a website or recommend some books that covers Tibetan daily rituals, prayers, and mantras? I know Om mani padme hum mantra already.
