Welcome to YT and congrats on your new addition. In regard to finding the best website for help with your Yorkie...well, in my opinion, you just found it.
As far as toys, mine seem to prefer plush toys with squeakers. They like them even better after they've effectively killed the squeakers and have ripped out all the stuffing. I try to avoid toys with hard plastic peices and just check them regularly to make sure there is nothing loose or tearing that could injur them or that they could pull off and eat.
