reading trouble

I have over 800 hours. I have done very little reading. I have a book (pdf) that has audio. I thought it might be good to try to read it while listening. If I look away from the words and listen, I understand a lot. When I try to read the words while listening, I translate, and understand less than listening alone. I have been trying this with podcasts/transcripts from Española a la Mexicana with less trouble. I really should be reading, but am having trouble getting out of translation mode. Any advice?

I have one question about reading. When you encounter a new word and you don't understand it, do you look it up or just continue without understanding that sentence? When reading in English (native) I do look up a word if I don't know it, but that is far more rare than with Spanish.
