"See, just adding factors is what I'm concerned about here. I've heard a bit about that, but I'm still working from the Monster Manual. I was curious, because animals don't gain further feats or skills along with extra hit dice, if that had been changed or if it might be enough of a mitigating factor that I'd end up with an ECL lower than the Hit Dice of the wolf."
That part has been changed.
Savage Species notes, as a preview of how things will be in 3.5E, that all creatures gain one feat for every three hit dice, just like characters do for levels, and they gain skill points at the same rate. I don't quite recall what the skill point increase is, but its there too. As a rule of thumb, I'd go for 2 + Int modifier per hit die.
Given that a wolf already has Weapon Finesse (bite) we can see that that's probably the feat it'd gain for its first hit dice. Since the wolf here has gained a third hit dice, it should thus also gain a second feat. When it takes it's first level, it'd gain another feat (5 hit dice + 1 level) since then it'd be sixth level.
Without any class levels, a creature's "class" skills are those in it's entry, so a normal wolf has class skills of Hide, Listen, Move Silently, Spot, and Wilderness Lore (to be renamed Survival in 3.5E). It can spend its skill points for its 3 additional hit dice on those normally, or on other (un-restricted) skills at cross-class price. Once it takes a class level, it gains skill points at the rate listed for that class, and that's class's class skill list is open to it also.
I think Luis might have something there for the reductions in ECL. I did forget to factor in penalties, such as lack of hands and certain item slots. To a degree though, your DM's (or fellow players if they can make magic items) might mitigate this somewhat with Opposable magic items from
Masters of the Wild. That shouldn't bring the ECL back up though. Taking the wolf's limitations into account, and ECL of +3 or +4 does sound better.
