I re-used those two metal coolant pipes and had leaks a short while later when I did mine. You probably have to remove the intake to get access to the whole pipe, but I would suggest replacing those now. Replacing them on an M62 is not nearly as bad a job as the N62. Otherwise, you will have to remove your new water pump if/when they leak (as i did...). My pipes looked better than yours, but the metal was etched where the o-rings seal.

Definitely replace all the hoses you removed, plastic expansion tank, etc.
