vibrations can be anything from barely noticeable to what is lovingly referred to as "Death Wobble". it doesn't sound like your vibs are that bad, so i'd start with a good balance and rotating of your tires. if that doesn't fix them, then either get an alignment or do it yourself(Click me

Also, I would double check all your front-end components and all bolts to make sure they are all tight...ie: tie rod, drag link, etc
