How do I power my mic?

So I've just gotten into electric with a Fat Strat and 2 amps
a Crate Vintage Club 20 and a Vox AD30VT.
Now I want to add my voice to the din.

I've got a couple of mics... SM58, and a couple of large and
small condencers. I've got a microphone pre I use for
recording into my computer. No mixer yet, I use the software
type.

Where do I go from here?

Thanks for the help
