Here's some information from orientation.
First off, you need some scrubs
--you'll need them first quarter (ask for them for Christmas!) For labs, you can wear any kind of scrubs you want (also, you must have close-toed shoes.) When you start your clinicals, you'll be required to wear the regulation ciel blue scrubs. You can get this color anywhere. As long as they're that color, the style doesn't matter. You'll be given patches with the DSN logo to sew on to your scrubs. I bought two pairs of the cheapest option, which cost about $45 (two shirts/two pants.)
We were reassured several times that while the first quarter is horrible (4 days/week), subsequent quarters you'll probably only be in school two days a week. You will be doing clinicals--1 hour of clinical work equals 4 actual hours per week. It was also mentioned that clinicals are often 12 hour shifts (but again, only 1-2 days a week, usually.)
You don't need to buy a stethoscope (until clinicals) or a blood pressure cuff (at all), but they can be useful for practicing at home. I bought the $20 stethoscope and the $12 blood pressure cuff, and my mother (who's a nurse), told me that I wouldn't need anything fancier for a long time, if at all.
Parking at DSN sucks. There's two lots across the street, but they cost $6-$7 a day. The school encourages carpooling. You can also take the light rail and then walk about 5 blocks (if you take the C line to the end.) We don't get a student discount through RTD.
Just one more note if you're considering nursing school: The instructors told us over and over again that nursing is probably not anything like what we think it is. We are not doctor slaves, and we're not babysitters. They warned us that the program probably won't be what we expected. They also said upfront that we're being trained to be "minimally competent" as defined by the State of Colorado. We shouldn't expect to really know what we're doing until we've been working for a few years.
Hope that helps! School starts Oct 9th--and I'm terrified!
