I recommend a thorough read through this

It will answer many many questions
Very nice reference. Search pdf on "draw weight" will give
recommendation. If into target archery it appears you do not want the
high draw weight that us US hunters would use. The only reason for a
high draw weight is that it is better if distances are unknown as you
shoot a flatter arrow.
