steering linkage boot/bellow easy replace?

[omodos]

hi all been a while which is good but just so happened as you do to look into the wheel arch with my steering wheel full lock to right and as you can see from pic the steering below is cracked flaked to bits, tried as best i could to patch up with gorilla tape until i get a repair (max heat it can take is 80c so wont alst long) ...didnt really see any grease flung anywhere so must be combination of this ahppening recently and there not being much grease in the below anyway....



Any ideas how major it is to get a new boot on? and will i need alignment done after this? any replies much appreciated
