RIT/NTID is a great school..better than CSUN and Gally in terms of the quality of education..it has several hundreds of deafies and are consists of both who sign and speak, plus they really help you find a job after you graduate which is a great plus
wheras in Gally, the whole school is deaf and almost everyone signs..plus it's a huge party school..you probably won't get much of a decent education from there since the majority of the students use ASL and their reading scores are incredibly low..fourth grade level..
CSUN is not a bad school..smaller deaf population than that of RIT/NTID..and hey, it's in sunny cali..where the weather is great all year--very contrast to the east in Rochester and DC..
so base your decision on who you would like to socialize with more--hearies or deafies? and check with the majors each of the universities offer and of course the location..make sure you visit each of the schools..
also, since you're a junior, and if you're seriously considering NTID/RIT, you should definitely do the EYF program this upcoming summer, like I did a couple years ago..it's a great one week program which helps you decide what you should major in and plus get a feel of the campus and meet other deafies..here's the site if you're interested:

although I didn't end up there, I was glad to go because of the great deaf people I met there, since I've been mainly mainstreamed my whole life..hoped i helped! good luck on whatever path you decide to take =D
