1. Look in the military aircrew section. You will find a wealth of this sort of information in the Joining- OASC sticky at the top of the page.
2. Your height/weight is I think marginal.
You are taller than my daughter but that is not the problem. As Whirlybird says you may be too light for a bang seat. I think my daughter was too light for a parachute too.
She is heavier now but very happy in her non-aircrew roll.
