I did a 1 1/2 punch front on floor and it was one of my favorite passes. I was working 1 1/2 punch front full when I had to retire. I can't remember if they're worth different values. Try looking on the USAG website.
www.usa-gymnastics.org. For this one I think it's really up to the gymnast. I personally think that there are more options with the 1 1/2 punch front something.
As far as the pac salto and the pike on shoot up to the high bar thingy. Pac salto serves as a bar to bar release, which is required for level 9. It will also serve as a bar to bar release and/or a second release for level 10. In level 10 the gymnast is only allowed to do a tuck on (squat on) once in their routine, I'm not sure if that rule applies for level 9 (i can't remember). The pike on shoot up to the high bar release will serve as a transition skill. I believe that there is no bonus for the pike swing down release skill. I believe there is only bonus for the pac salto if it is connected before or after a C or D level skill. I will ask at work tonight, one of my coworkers is a judge.
As far as beam goes; go for learning the handspring tuck or handspring layout. For level 9 I don't believe it is a requirment to have an areial skill (flipping skill). They do however have to have a flight series, such as handspring handspring. I can't recall if it would be bonus to do a handspring tuck as a level 9--again, i'll have to ask at work.
Adding a jump before or after the standing tuck would meet a gym-acro requirment (leap/jump and acro (handspring, roundoff, back tuck, etc). I believe there is still a gym-acro requirment. I don't believe there would be bonus for that one, but there might be depending on the skills and jumps.
