I would say that it was mistake to put down Choice #3 on your Preference Sheet at the end of the night, if you had no intention of ever joining that group. Also, if anything, if you didn't want Choice #3, skipping their Choice #3's Preference would probably have send the message, loud and clear to them.

That being said, I do think that your Rho Chi was also somewhat in the wrong to direct you to still put down choice #3: "I told my Rho Chi that I really really really wouldn't be comfortable with my 3rd choice and she said there was only a slight chance of getting it (bad advice) and I should put it down anyway".

I also don't know what your campus is like, but if you are extended a bid and then don't join, you could be viewed as...ahem..."damaged goods" next year and it might be even more difficult to get a bid from your top 2. I don't mean to be harsh, but I think it's important that you are aware of all of the possibilities.
