I have a iPhone 4 and set up iCloud on my device, including the Photo Stream service. Everything seems to be set up fine and I have the option to select Photo Stream in Photos.app.
However, the message I get when tapping Photo Stream is that all new photos will be transferred into the Photo Stream.
How do I get the current photos in my phone to show up in my Photo Stream?
Yes, you can ! You have to turn it back on, take a picture and wait for it to upload to iCloud. Then you turn it off and and confirm the warning that says that all the pictures will be deleted. The album will then disappear.
A photo stored in the Camera Roll is permanently stored on your device (until you delete it). Only 1,000 photos are saved in the Photo Stream on an iOS device, so if enough photos are uploaded to your Photo Stream the old ones will be purged. (But a Mac or PC will save all of the photos in your Photo Stream by default.)
According to Apple, the downscaling does only apply on iOS devices — if you have Photo Stream set up on your computer, those photos will be full-resolution.
On your Mac or PC, your photos are downloaded and stored in full resolution. On your iPhone, iPad, iPod touch, and Apple TV, your Photo Stream photos are delivered in a device-optimized resolution that speeds downloads and saves storage space.
Yes — to delete multiple photos, just tap the action button in the upper right corner, select some photos, and tap the Delete button.

Given that this question is a few months old, you may have already found an answer, but I figured I'd provide one in case anyone else comes to this post looking for an answer to the same question.
While I don't know of a way to add photos from the Camera Roll to the "main" photo stream retroactively, you can add pictures to shared photo streams. Those will sync up with iCloud and any iCloud-connected devices, just like the "main" photo stream.
