USC rush is very competitive, and I know girls who have been burned by not having recs during that recruitment. You should try your best to get recs for every house (ask family friends and teachers to find people from the other houses) so that you have the opportunity to look at each one without worrying about not having a rec.

You mentioned that you don't know which houses you want to rush yet... and that's a good thing, because you probably don't know many of the chapter members yet! Don't try to decide which chapters you are considering in order to find recs for those chapters... get recs for every chapter so you can make the best decision once you're at USC and you've had a chance to meet every house. The sororities you have recs for will not have any way of knowing which other houses also have recs for you, so it can only be positive to have as many recs as possible.

EDIT: And you should send a resume and photo to the people who are writing your recs, yes. They will use this info to fill out a recommendation for you and they will take care of sending the rec to the chapter for you (you should not have any personal contact with any of the chapters).
