Hanger adjustment not necessary unless you bent it since you put the different wheel on. Different wheel, different cassette position = minor cable adjustment and re-check the limit screws.
Only tools needed are your hands to twist the adjusting barrel on the RD and possibly a flathead or Phillips screwdriver for the limit screws. Careful with those screws though, if you do it wrong the chain can jump off into the spokes possibly destroying your rear wheel and RD all at once! Not fun.
