Try buying this book:
Lonely Planet Phrasebook - German
I personally find this series of phrasebook particularly useful. I have one for Japanese, and German, and I'm planning to buy some more for other languages. It's quite handy when you're travelling abroad, but it's equally handy when trying to learn a new language. The only problem is...that you'll have to rather good at the English language.
But overall, it's a brilliant series, and I'd strongly recommend it to you.
