The Parametric EQ 2 works well for cutting and even better for filtering, not so much for boosting but I usually cut and HPF or LPF before I boost 9 times out of 10 anyways ... Waves REQ's are fantastic, you could probably grab the demo off of their website
Fruity Parametric EQ2 is all you need bro. I also use Ozone's EQ for it's mid/side and matching functions but you won't find many free plugins better than EQ2, it's easy to use and have all the features you need (plus a spectrum visualisation, which is awesome).
