At a complete SWAG I'd say in the 590, maybe 600 range.
The utilization will help, dropping one late from several in that time frame may not make much difference at all, though every little bit helps.
It's hard to say, recent derogatory information tends to have a severe dampening effect on the rest of the algorithm anecdotally. Given that it's the king of the hill in the model, I suppose that's nearly a given.
ETA: I'd love to hear what your score does do if you don't mind sharing.
