Contacting graduate coordinator for a campus visit?

[shanrina]

Hi, everyone. I'm currently drafting an email to the graduate coordinator of one of the programs I'm applying to, and I'm having a really hard time figuring out what to say to her and what to just say to the professors I'm planning to contact. Should I tell her which professors I'd like to speak with? (My logic is that if I tell her then she'll be able to tell me that this event is going on during one potential weekend and Professor X will be out of town on that weekend, and so on, before I contact the professors. Is discussing who I hope to meet with in an email to the grad coordinator before I talk to the professors themselves some kind of faux pas?

Also, is it okay to mention associate and assistant professors I'd be interested in working with, or do they just want me to mention full professors?

Thanks for any input--I'm probably seriously overthinking this, but I can't seem to make myself send it without envisioning horrible consequences after accidentally offending a lot of professors at my first choice school.
