Love me some Pink Floyd.
But onto your questions...
I don't know where to start from, really, because I don't know what symptoms the addition of depakote was intended to relieve. Were you depressed and feel that it might be making your manicky? Were you manicky and feel that what you've got isn't enough? I don't know, so my answers are pretty general. Plus I'm not a real doctor. I just play one on TV
There is a difference between what is too much when you are in an actively manic state and when you are in the maintenance phase. Only your doctor can determine that. You are on quite the cocktail but that doesn't mean it's "too much." Only your doctor can tell you what is too much. As a point of reference though...When I was in the hospital, the doctor who treated me said it was common to have more that one mood stabilizer in place for severe bipolar. You have several.
As for klonopin, yes. It is a benzo. Benzos can mask manic symptoms. At the same time, klonopin is used to TREAT bipolar. I don't know much about it though. I wish I could be more helpful.
Do you have family or friends monitoring you? If not, you probably should. At least until you can direct these questions to your pdoc or your symptoms abate
