Your castle nut has been staked well by the sounds of it. Don't use mag vice to undo it... I think what @northdude meant was an upper vice block to hold it firmly in place - Like this one.

Is it imperative that you install a sling plate? Personally i'd leave it in place. What about QD sling attachments on your stock?

Not imperative, but would be nice at some stage. I've got that exact block, but it doesn't hold the upper and lower, just upper. I'll probably just leave it, and if I ever need to take the tube off I will put it on then
