the crickets won't be able to climb out of the bowl. they cannot climb glass. Lynn's suggestion of covering the sides of the glass is spot on. it will make your little phib friend fee more safe and secure and he/she will acclimate easier.

as far as a buddy for him, i would suggest getting the hang of it with the one you have for a few months and then go from there. the most important thing you can do is heed any and all of the advice Lynn has to offer. the lady knows her red eyes. plain and simple. in my opinion, going against her advice would be foolish and detrimental to your frog.
