This has been talked about in the past by myself on others. The short answer is "no there isn't."

However more detailed is you need to tell the ripple what to do and it won't do what you are describing. It will do all tracks or only the track you are on. You have option to move all events or all events, regions and markers. You can "lock" tracks, but it is not as easy as, IMO, you can in Premiere. Vegas has a sync issue if you aren't careful and that does tie into this issue, they do go hand in hand. For me working in Premiere is better for this - if I want to keep certian tracks in place all I have to do is click the little padlock icon on those tracks. And this ties into sync because in Vegas when you make a cut the first part of audio and video stay "locked" but the rest doesn't, again IMO, Premiere handles this better. So with Vegas if you grab onto the video to move it, the audio stays in place if you aren't careful. (Likewise bring in picture and try to just click on audio and hit delete - it can be a bitch to do only this unless you check several settings.) So in Vegas you sort of need to group both audio and video and "lock" them. (And this also ties into the whole nested timeline discussion with Vegas)

Like you say - "I can Select Events to End, then do Lock, and get 'em, but it seems somewhat cumbersome." And I think more than you and I would agree with that comment, especially when you tie it into the sync and "grouping" issues.
