Well I know you've made up your mind so there's not much point discussing it any further BUT I'd like to add a couple of points.
I've been googling the question and most people believe in 3.0 you couldn't use Animal Growth but in 3.5 you can. I will have to do more research as to the reasons. Enlarge Person should work if the Druid is a humanoid because in 3.5 you retain your original type. So you could wildshape into a badger but you are still considered to be a humanoid. None of this matters for this game because the DM has said you can't add size onto anything that increases your size. But it's still something to look at for a regular game.
It seems the wildshape rules in Masters of the Wild are thought to be better than the 3.5 rules. I haven't taken a look yet but I will because there's a druid in my RL game. Unfortunately he does not play a druid very well because he relies on the rest of us to tell him what to turn into or cast. It's quite annoying.
