Tactics trainer and chess mentor once a day for a period of time should improve your ranking substantially along with regular game practice.
Your individual rankings seem good. Having a lower bullet ranking in comparison to your standard game indicate good and careful thinking.
I wouldn't worry about your bullet ranking because true chess requires lots of thinking time which you obviously have.
Hope this Helps
