I take the punctured tub off and put the spare straight on - getting it back off at home shouldn't be a problem. Not sure you could remove any glue on the side of the road anyway
On my old corsa's I had two options (1) add an extension on the existing valve and (2) remove the valve and replace with a longer one. Don't think there is much between them but I felt more comfortable with the extensions as I wasn't too sure about messing with the valve/innertube interface.
My 2 cents
I put Revo in my brand new Veloflexs - seems okay
With sealant in I carry a spare glued tub only
