I've reached out to several providers at once in the past and just ignored the rest when I hear back from the one I really want to see, is this considered rude?
Please consider this: If you are sending your info ("references and things") in the initial contact, the providers might immediately set about screening you, then follow-up to agree to the date once you've passed muster.
Since you have "several" backups, you have now wasted those providers' time, plus that of your references too.
Then you not only don't schedule, but you also fail to reply? This behavior can get you Blacklisted as a TimeWaster.

If I ignored someone after initial inquiry (with my reference and things), will it affect my future bookings with her?
Let me be clear: Ignoring someone is simply bad manners. Please don't do that.
Personally, I feel the polite thing to do is to reply with an excuse such as: "I'm sorry but my schedule changed and I can't make that day work anymore; I'll try again another time!".
Yes, she might well assume that you booked someone else but I'd personally much rather get that than no response at all.
The approach you've been taking can absolutely affect ever meeting your backup ladies as well as potentially impact your client reputation. The latter could lead to difficulty in scheduling with anyone.
As with anything, it's a good idea to try to put yourself in the other person's shoes, and imagine how you'd prefer the situation be handled.
