Unless you go for an old version you will need a new 11sp hub as well... I just made that mistake, annoyed the feck out of me as I only realised my ridiculous mistake as I was left with the 12 tooth cog in my hand while I was trying to fit the cassette..! I'd already fitted everything else... IDIOT!
Internal cable routeing I have no idea but I always assumed you'd use the old cable to pull the new cable through?
Tools - Allen keys, Shimano bottom bracket removal tool, wire cutters, big spanner and chain whip, small screwdriver, pedal spanner...
