Hey Red,
Welcome to the site, enjoy.
You mentioned finding out what is a good bike for a girl, well there isn't a good or bad one it depends on what you want. There are lots of different styles in each size group, you'll find that some of the ladies on here have no bike and are not pilly's, others are regular pilly's then there's the biker girls from125's on L's after CBT to"MUCH" bigger bikes.
Top and bottom is it's your choice.
Have fun.
