I would recommend you try to figure out what kind of singer you are. This might help you (along with proper breathing) to know what your goals are.

Are you a John Lee Hooker or a celine dion? A Kid Rock or a Don henley?

Have you ever heard that clip of Celine singing an AC/DC song? Just nasty. Not everybody is meant to sing every song the same way. Find out what direction your voice naturally wants to go.
Some people have vibrato and some don't. Don't force it too hard if it ain't natural.

I've sat through a few Church services where everyone tried to sing along with the soprano worship leader that added a 3 second vibrato to the end of every phrase. Definitely not for everyone. The simpler the singer the better.

I found that my voice is kinda similar to Delbert McClinton, Todd Snider and Tom Petty. I look to these guys for inspiration, tone and phrasing.

Just something to think about.
