Do I need 4 1000lb casters or would 4 250lb casters work?

If it were uniformly distributed load, each leg would support 250lb,
yes. But you would still want cushion/margin over that, of course.

But since it isn't going to be uniform, you need something that has a
fair amount of cushion over that minimum; you'll have to guesstimate how
much imbalance that might be and go from there.
