Greenlady, CONGRATS!!

I'm stressed (like you were before), especially since I haven't received my interview letter (I filed everything on May) I'm on a F-1 visa as well and my husband is a US citizen. Did you have to tell your school about your changing of status? It took INS about 5-6 months to send you the interview letter!! Is that the processing time for F-1 students applying for the GC? Any comment would be appreciated. Thanks.
I was an F-1 before I applied to adjust my status. I think you should definetely let your school/international student services know that you filed I-485. I think they will eventually get to know that you did so because your filing for I-485 makes your F-1 visa useless (when you apply for F-1, your only intention is to go to school and return back to your country which they ask you swear that you will not stay after you are finished with your education. when you file for I-485 you let the USA know that you are here to stay and not going anywhere and heck with the F-1, becasue of a certain reason which could be work, spouse, political etc.) i think the most important reason you should let your school know that you are not an F-1 anymore or filed I-485 is that filing I-485 will entitle you to pay in-state tuition. you should go to your school and ask them bona fide resident form (if there is such a thing). along with this form, your I-485 receipt and another proof that you can show you have been a resident of the state more than a year (probably they will give you a list of acceptable documents) will be suffice to pay in state tuition next semester. again this may change school to school and it did work out with my school.
I dont know if being an F-1 could cause your case to go slower than many other cases. honestly, as an F-1 you will never over stay your visa as long as you are a full time student, there are illegals in this forum who got their greencards before even their documents got to the USCIS (figuratively speaking) i start to think that the length of a case more so depent on the officer and/or the office your case is in. this individual might have a complicated case right before yours and you might be stuck behind this case until it is resolved. Again i dont if this is true but there is no other explanation to why some cases might take longer than the others.
hope it helps. good luck
