I've got a $600 budget for an amp head and about the same amount for a cab (but I can save up more).

I'm interested in the:

-Ampeg B2RE Bass Head

-Gallien-Krueger 700RB-II Bass Head

-Gallien-Krueger Backline 600 Bass Head

I'm looking for a variety of tone, not to fussed about the volume though, tone is more important at the moment. I'm not sure about what cab yet though.
Out of those, I'd definetly go with the Gallien-Krueger 700RB-II. I've heard great things about it. With a $600 cab budget, I'd look at some 4x10s. Look on your local Craigslist, I often see people selling bass cabs on there for great deals.
those are solid state arent they? i know the ampeg is but not sure about the GKs, think they are
^ You'd be surprised. Graphic EQ's rock, but a well made active parametric EQ can be just as good.

EDIT: Also, a graphic EQ won't make your amp or bass sound exactly like another amp/bass.
