I believe that if you have checked Automatic Import in iPhoto>Preferences>Photo Stream they are safely in your iPhoto library. I tested this myself by deleting a photo from camera roll that was recently imported to a photo stream monthly event in iPhoto and it stayed there. You could do the same by taking a new photo, closing Camera and waiting for it to be added to photo stream and iPhoto, then deleting it from your camera roll.
To delete them all from you phone, connect you phone to your computer, open Image Capture (in your Applications folder), select the photos you want to delete (select a range by clicking the first photo, then shift-clicking the last one, or select non-contiguous photos by Command-clicking), then click the red circle with diagonal line icon at the bottom (see right icon on image below).

As a bit of an aside:
An easy way to check whether a photo in iPhoto is safely in the library or just in photo stream is to ctrl-click on a photo, if it says show in library it is safe, if it says import it is not and should be imported.
If you ctrl-click on multiple photos and just one of them is not in the library it will say import, this can be quite useful if there is any uncertainty.

That's because you are looking in the library (either through an album or an event for example). If you see the photos in the library you know they are safe.
But since your photo stream photos may well be in more than one event or album, you may have to look through many to make sure all your photos are safe or if you look at all your library at once through the photos option in the library list, it may well be too large to find them quickly.
By quickly selecting every photo in photo stream and ensuring it says 'show in library', you know that everything in photostream is safe in iPhoto.

Got it. I was in "Events" but navigated to "Photo Stream" and did the ctrl-click and saw "show in library." Thanks so much, very helpful!
