What is the best way to insulate exterior of older home?

I have an older home in Toronto with plaster lathe walls with no insulation behind them.  I want to insulate the walls but not remove the plaster as it's still in excellent condition.  My house goes right to the property line on two sides and the exterior shell is cedar board/insulbrick covered by vinyl siding.  I would like to stip it to the cedar board, putting a wrap over it, but then what would you recommend for insulating after that given my narrow confines?  I really can't extend much more than a couple of inches without encroaching, three max...

I've a question Mike,

If Geoff were to strip the siding off the outside, then drill and inject the cavities with dense packed cellulose from the outside before installing the peel and stick membrane, then install the continuous insulation to the exterior before his new siding, could that work and boost the wall insulation significantly?
