1. your UGB is 700M, given also your resolution is <10bit, and assume everything is linear, your max allowed sampling is about 130MS/s --> this is a very optimistic estimation. but I guess it's sufficient for you.
2. your AC response showing some zero and pole closer to each other, is that right? if this is the case, then it will severely impact your step response. try to push out your zero (if you can, show me your opamp topology)
3. I guess the slewing rate is good. so fix 2 first.
