I agree that they should give you better guidance as to your budget before you accept the position.
As for contacting your predecessor, I wouldn't bother. You're not going to get an honest answer out of anybody; everything said about the other will be heavily influenced by the "breakup".
I'll summarize what happened: your predecessor picked a fight, and lost. Leave it at that. The specifics may not be the least bit relevant, won't change what you're going to have to do, and will likely taint your views of your coworkers.
Go in with a clean slate, and make the job your own. Maybe you'll need to pick the same fight. Maybe not. Why worry about it, when you're sure to have plenty of immediate problems.
And again, I would expect better budget guidance before accepting, regardless.
