Please see the stickies at the top of this forum. Yes.

Yes, the horse has been beaten well beyond death and into a pulp. Carriers don't announce OS update releases. You can monitor the latest OS threads stickied at the top of the forum. 4.5 has been out for quite some time. None of the stickied releases are betas -- as has already been mentioned forum policy prohibits linking to betas.
You don't have to wait on your carrier. An 8310 is an 8310. As long as you match up the model numbers (must be identical) you can cross-load OS's. They're all produced by RIM anyway. It's actually quite rare that any of my BB's have an OS from the carrier that sold the BB. Your carrier-specific settings are in the service books pushed by the carrier's network -- not the OS itself. There are some carrier-specific apps (TMO 5, at&t PTT, etc) but loading or not loading these is pretty well covered in the stickied threads.
As for potential issues, again, read the stickied threads. There are posts and discussions from those who have upgraded. Those are your best resource for specific information on specific releases.
