If you need to divide the procedures into different functional areas and you're using SQL 2005 then you might want to look at using schemas; conventional best practice prior to 2005 says that all objects should be owned by dbo so you probably don't want to head in that direction.
I agree with the concept of naming procedures with the predominant table or view being accessed and describing the action being performed but I would reverse the order of the two. Having the table/view name first makes it easier to identify the procedures that need to change when the table/view is changed since they will all sort together.
As Ian said, I would also throw out the "usp_" prefix; it's just noise and doesn't pose a problem unless you have a table or view called "sp" (unlikely).
This was a good, simple presentation of a common topic. It would be refreshing to have someone write an article that looked at several naming schemes and compared them. I am partial to mine but would be open to other suggestions. I have promised an article or two already and not delivered so I'm not going too far out on a limb here
