Check out KVR Audio for EQ plugs.
Otherwise, the ones that are fairly basic and that I use and like are:
Bootsy's Plugins: varietyofsound.wordpress.com/downloads/
BootEQ MkII and Baxter are both EQ plugs, but BootEQ is probably more for a per-channel/mixing use, and works nicely with vocals. Baxter is more for the master channel or for mix buses.
I'm currently using BootEQ on a project to eliminate some issues with some noises on some tracks, and to help give the vocals a bit of body and presence. It's a pretty good sound IMO, and the built-in pre-amp sim is a nice option which can be turned off.
For something a little more flexible, try:
Fn Equalizer or EasyQ They're both pretty good and easy to use.
That should be enough options to do what you want to do.
